SOV/124-57-5-5541 Translation from: Referativnyy zhurnal. Mekhanika, 1957, Nr 5, p 61 (USSR) AUTHOR: Kovalev, Ya. T. TITLE: On a Submergence Criterion for a Ci rcular- section Bottom Outlet Through Which Water Flows Under Pressure (0 kriterii zatopleniya donnogo vodospuska kruglogo secheniya pri napornom dvizhenii) PERIODICAL: Sb. nauch. rabot. Beloruss. politekhn. in-t, 1956, Nr 54, pp 63-70 ABSTRACT: The author confirms the earlier finding of other authors to the effect that an.error is generally made in the calculation of the discharge capacity of pressure-type water conduits in two specific cases: 1) if the effective pressure head is assumed to equalthe difference between the head-water level and the tail-water level when the tail- water level ties above the location of the center of gravity of the area of the outlet cross section of the conduit; and 2) if the effective pres- sure head is assumed to equal the vertical distance of the head-water level above the location of the center of gravity of the area of the out- let cross section of the conduit when the tail-water level ties below said center- of -gravity location. It is recommended that a water- Card 1/2 conduit [outlet] be considered unsubmerged whenever the actual SOV/124-57-5-5541 On a Submergence Criterion for a Circular- section Bottom Outlet (cont.) tail-water depth ha is smaller than the depth h2. When the opposite holds true, the outlet must be regarded as submerged. It is necessary to point out that merely- .- establishing a satisfactory submergence criterion for pressure-type water conduit.~ does not in itself solve the problem of determining correctly their discharge capa- cities (see, for example, Faktorovich, M. E., Izv. Vses. n.-i. in-ta gidrotekhn., 1947, Vol 34). The a-uthor's recommendations to the effect that the coefficient be used to allow for the pressure-force impulse in a water pipe's outlet-section plane are debatable. His method of proving the validity of the numerical values that he arrives at for this coefficient is unconvincing, because his correlation of experimental data with the calculation results that include this coefficient is based upon the very same experiments and relationships, that he used to Obtain the values in the first place. Consequently, the numerical values which he gives for his coefficient t in this paper cannot be applied to conditions differing at all signifi- cantly from the particular conditions that obtained in his experiments.

Permanent storage facilities must be carefully checked for cracks, splits or improperly adjusted fittings. Foundations should be tamped down and covered. The covers of buried, or semi-buried, containers should be carefully checked. All valves and gaskets should be checked. The heating elements in the tanks require a great deal of attention so they will function proper- ly in cold weather. The area must be cleared of snow so each dump must have snow removal or clearing equipment, such as a "Belarus" mounted on a truck chassis. Other equipment for this purpose includes MS-49 snowplows, or trucks equipped with L 10747-67 ~CC NR- AP601679-1 0 hydraulic scoops, or snowplows. A DIXM-5 handcar will clear snow from railroads. Dry sand should be kept on hand to reduce slippage on ice. All vehicles should be provided with tire chains and entrenching tools. When sectional pipelines are used to connect tanks all snow and ice must be removed and they must have the proper slope* If the temperature is below -30*C tanks made of rubberized cloth must be heated prior to folding or unfolding. Rubber hose too must be heated (especially new hose) under such conditions. Winter servicing of equipment calls for the full attention of all personnel, strict supervision of the work by commanders, and a constant increase in the level of technical knowledge of apeoialists and commanders.

Application of the Method of Electric Resistance in Investigating the Corrosion and Destruction of Steel at High Temperatures kt PERIODICAL: Zawodakaya laboratoriya, 196o, Vol 36, Nr 3, pp 296-298 (USSR) TEXT.- The time passing until cracking in the expansion of samples was determined by measuring the electric resistance of these samples. A special device (Fig 1) was used in which an indicator measures the increase in length of the sample with an acouracy of 0.01 am. The tensile stress of the sample is gradually increased by means of weights and rotation of a disc. The experiments were made on a wire sample (diameter 3 mm, length 300 mm) of I KWN909teel. The electric resistance of the sample is determined by a double Be_n_s_o_n_b_r1dge over a measuring length of 20 mm. The temperature is measured by a thermocouple and a PP-1 potentiometer. Tests were carried out at 7009 750 and 8,';Oo, the sample being placed in air or in a salt solution (41.6% V20 59 11.2% Na,2so4, 16% A120 39 16% Fe2039 7-2% S1029 6.4% NiO, and 1.6% CuO). The curves of the change in electric resistance of the sample during a test at 8000 are given as an example (Fig 2). The curves show a distinct salient point short before the fracture of the sample, i.e. the electrie resistance rises sharply. Metallographie investigations showed that the sample was cracking after the rise in electric resistance. If, however, loading is inter- rupted before the rise in elootrio resistance, no cracking is observed,, The Card 1/2 KOVALEV, YE.

Silicide diffusion coazings were produced at 1000, 1020 and 10500C by soaking for ? - 6 hours, Alumi- nizing was carried out at 1000 and 1 .10000, soaking for 4 - 6 hours and chromiding in vacuum at 10000C for 4 - 6 hours, 7300C was srz lected as the temperature for corrosion testing, this being the na- ximum service temperature for guide vanes of a gas turbine. To se~- leot the mode of application of the corrosive mixture to t*he speci- menso at which the rate of corrosion of the specimens at elevated temperatures should approach the intensity of destruction of the alloys in the course of service of the gas turbine planiq Two me.- thods were inTestigatedg Immersion of the specimens in molten cin- der and application of a suspension to the specimens at room tempe-- rat-ures (painting). On testing the above coatings in an atmosphere of air �n contact with cinder (10 and 41.6 % V20 5) at -t300C, sili.- cided specimens exhibited the greatest resistance against corrosion by vanadium pentoxide. The resistance of aluminized and a'-Ium--;-no- sili-cided specimens was lower. All coatings, apart from si-licided ones, failed on testing for 500 hours in contac--~ with cinder at 73006.

In the presence of S102 in air atmosphere, the rate of corros:'Lon of alumino-silicided and aluminized specimens is the same as the rate of corrosion in pure air. Chromided and silicided spe- cimens exhibit high stability under these conditions. A combination cementation coating (~i and Al) gave less protection to the steel B1417 against vanadium pentoxide than a coating consisting of one of the individual elements,, On periodically cooling thespecimens (cooling 40 times from 730 to 2000 within 15-20 minutes), no exfo-, liation and destruction of the protective layer of chromided and silicided specimens occurred. No cracks or ruptures in the diffu- sion layer were observed on water quenching silicided specimens from 11500C and the adhesion of the coating to the base metal re- mained unimpaired.

There is no agreement in the literature as to the mechanism of this type of corrosion and for this reason the authors investigated the process of oxi- dation of steel specimens heated to temperatures of 600 - 50 0C in air, in contact -with and without vanadium pentoxide and a mixture of vanadium pentoxide and sodium sulphate. A chromium nickel austenitic steel EI-417 (0.11% C, 1.24% mn, 0.76LC, Si, 24,1(), cr, 18.47%. Ni, 0.022?! P and 0.01370' S), after hot-rolling without thermal treatment, was used for the investigation. Specimens were prepared in the form of plates 20 x 10 x 17 mm.

For comparison. temperature of 600, 650, 700, 750 oxidation of specimens of the same composition and at the same temperatures but without contact i1rith the ash or vanadium pentoxide, was carried out for 1, 2. 4, 8, 16, 32, 64 and 100 lirs. The coating was renewed every PO hours in the oxidation tests of the coated specimens~ Removal of corrosion products froin the specimens was done electrochemically. It was found that, on heating in air, steel BI-417 oxidises according to the parabolic law (with the exception of the first stage during the first four hours) and., on heating in contact with V 205 or with the above itiixture - according,, to the linear law in the whole temperature range investigated (650 - 850 0C).

Thus a rapid oxidation was observed only in the presence of liqu:1d V205 phase and low melting iron vanadatos and their mixtures with iron and chromium oxides. The oxide film of specimens oxidised in air was analysed by electron-diffraction methods and the corrosion products of specimens oxidised in contact with V205 and the mixture were submitted to X-ray and electron- diffraction analyses. The results obtained indicate that tile film formed on oxidation of specimens in air (not in contact with V,O .~. 5 or the mixture) consisted of solid solutionsof the spinels FeCr204 and NiFe204. The scale formed on the specimens oxidised in contact with V20 5 consisted mainly of a mixture of solid solutions of (x-.Fe2o 31 a-Cr205 and V20 5' In the scale of specimens in contact with the mixti~re, in addition to the above o~zidcs of the Card 3/6 s/l8o/61/ooo/oo6/oil/02O On the mechanism of ....

Local high quality bauxite and limestone mined in the TSYUANS1 province served as raw material. By employing the sintering methodo different compositions of kiln charges were tested, mainly using.low bass calcium aluminates - CaO.Al 203 and CaO.2 Al203- Fineness of grinding was found to be from 2.9 to 6.5 % on 0085 slaves- Calcination temperatures ranged from 1350-137011, and were controlled by optical pyrobeters. Based on 19 test charges, the contents of main oxides varied from 4.9-9.84 % for SiO 2, 45.71-59.26% for Al203 and from 30.0-39.42 ','o for CaO.

Receivedt 3 / 1957 Reviewedl 4 / 1957 ABSTRACTt The sources of rectangular shape have certain advantages in connection with the radiation of some objects for cold sterilizing eto. One of those advantages is the possibility of creating a steady radiation field, which is very important in some oases. The authors computed the radiation field of a rectangular source with any dimensions on the following conditions: 1) The radio- dispersed evenly over the whole field. 2) The active substance is . sample has neither eigen-absorption nor eigen-scattering. Under such conditions it is easy to show that the dosage output of x-radiation at the measuring point, which is caused by a source with the side-lengths a and b and the surface density d-of ra- dio-activity, depends only on the relative dimensions n - b/a and the relative distance m = h/a from the assumed point. Without re- ducing the general character of the calculations the values of n can be restricted to the interval 0 4 n .4 1, for the longer side of the rectangle can always be denoted with a. The results of these calculations are shown in a nomogram which is suited for 2 Card 1/ 3 practical use. Computations were carried out forG'. 1 mg-Xq.Ra/OM PA - 2267 The Radiation Field of a Reotargular Source. for the most frequently oocuring relative distances (0,01.6 m ~6 5) and relative dimensions (0,025 < n 4 1). When using the nomogram the dosage output P of the W radiation of the rectangular source can be computed w1th any surface densi- ty 6- according to a formula P - 6-.P (h/a, b/a), where P(h/a, b/a) is taken from the nomogrAam. This.formula permits the de- termination of the radiation field for the case that the pro- jeotion of the measuring point is identical with one corner of the rectangle. In all other cases of a reciprocal arrangement of source and measuring point the radiation output of the (r -radiation can be computed as followst A formula for P A is given in case that the projection of the measuring point is within the source. All terms of this formula are taken from the nomogram and therefor the case under investigation ean now be reduced to the preceding one. In a similar manner the dosage output at a measuring point the projection of which is outside the source may be found. Thus the here duscussed computations apply to.any arrangement of the source with respect to the measuring point.

This is the case when. the analytical expression given in Ref 2 is used for the accumulation factor. This formula applies to wide ranges of the 7-radiation energy values and protective thicknesses. When this formula and the notation assumed (Ref !) are used it can be shown that the power of a y-radiation dose emitted from the tiuncatied cone covered by a protective layer can be determined by the foTmula (2).

Some special cases which are of interest for practical work are investi- gated: I) Radiation of an infinite half-space through an ab- sorbing and soat'--taring protectiVe layer. The formula (3) (accordiug to the method descr-ibed in Ref 1) obtained by the inte6rat-ion cf (2) is turned into formula (4) in this case. 2) The radiation of a truncated cone of infinite thickness thrc-ugh an absorbing and scattering protective layer: formula (5). - In the cease where the protection lacks the multiple sc:at,terinc ira th-6 soux-.,e itself can be taken into account. For thi5 purpose the formula (1) is used with other values for the ao~cumulat_-.'c-n factors. In the same way as with (3) the formula (7) is determined for the power of the y-radia- tion dose (emitted f-rom the bruncat!~-d cone taking into ao,:tount the multipla s(,attering without prutective layer).

TITLE* Geometrical Correction Factor for a Cylindrical Ionization Chamber (Popravochnyy geometricheskiy faktor d1ya tsilindricheskoy ionizatsionnoy kamery) PERIODICAL~ Pribory i tekhnika eksperimenta 9 1959, Nr 3. pp 63-66 (USSR) ABSTRACT: In the dosimetry of point sources of y-radiation it is necessary to determine the true ionization density from the readings of the ionization chamber. This is due to the fact that.frequently,,ionization chambers are used whose linear dimensions are not sufficiently small in comparison with the distance between the point source and the geometrical centre of the chamber, An expression is obtained for the correction factor for the case where the source is at an arbitrary distance from the centre of the chamber in the radial direction (Eq 8). Graphs are given (Figs 2 and 3) of the values of the geometrical correction factor for a cylindrical ionization chamber.

This problem is dealt with under the following'assumptions: 1) the source is assumed to consist of an infinitely thin radiating plate 2) the active substance is assumed to be equally di~ptrl- buted on the surface of the source. Figure 1 shows the geome- trical conditions for which the rS-ray attenuation and the dose rate are in the following theoreticaliy investigated in de- pendence on the distance...-The.formulas obtained are discussed and demonstrated by means of practical examples.
