K ratio of specific heats

Webapplies, where “k” is the ratio of specific heats, c p /c v, for the gas. An increase in gas temperature accompanies the compression. The use of the adiabatic process in calculations enables the designer to work from Mollier diagrams. This is closer to being correct for an internally cooled compressor than an uncooled machine. WebSpecific heat ratio in the superheat transition zone is revised with the method and then a regression equation is fitted. By introducing the regression equation to calculation of steam critical mass flux, the error of the result with ideal gas method reduce to ±0.9%, achieving higher accuracy in flow rate calculation of supersonic steam nozzle.
