These tables have been prepared for compressible fluids of common use. Long and detailed tables in a wide range covering a number of values of γ = cp /cv besides being expensive are not fully used by a majority of students. Various formulas which form the basis of the tables are also included which will be useful for ready reference. With numerical work of this magnitude it is highly probable that some errors may have crept in; reference to these errors and suggestions for improvement will be highly appreciated. The ranges of various tables have been chosen according to their importance and frequency in use. S.M. YAHYA ww w.

Gas dynamic properties of some vapours and gases It is well known that the specific heats (cp and cv) of gases and vapours vary with temperature. Therefore, the values of the ratio of specific heats, Gas constant and the maximum mass flow parameter also vary with temperature. These have been tabulated for a range of temperatures at given values of pressure. Only some of the commonly used gases and vapours have been chosen for these tables. γ = cp cv R = cp − cv a = γRT A * P0 Lγ F 2 I =M G MN R H γ + 1JK γ +1 γ −1 OP PQ ...(1.1) ...(1.2) ...(1.3) 12 arn w T0 En gin e Formulae ...(1.4) ww w.

Le arn For lower velocities dynamic head is measured in millimetres of water (mmW.G) on a vertical or inclined tube manometer. At higher velocities dynamic head is more conveniently measured in millimeters of mercury (mm Hg). Tables 10.1 and 10.2 give approximate velocities and Mach numbers at the prescribed values of pressure and temperature; the approximation is less realistic at higher Mach numbers on account of increasing deviation of the actual flow from incompressible flow conditions. Therefore, at higher Mach numbers Table 10.2 gives only rough estimates of the velocity and Mach number. On account of this discrepancy the use of Table 10.3 is recommended at higher Mach numbers. ww 11. Measurement of low pressures on inclined manometers. Low pressures and velocities of gases can be measured by magnifying the actual manometer deflection (h) many times. This is done by inclining the manometer tube/tubes by angles shown in table 11.

Static pressure drop (pr = outlet pressure/inlet pressure) in gas pipe lines Compressors are required to raise the pressure of gases to compensate for the pressure drop in long pipe lines. In these tables values of static pressure drop in the pipe lines have been tabulated with the assumption of isothermal flow. The flow has been further assumed to start with a low Mach number of M1 = 0.02.
