Steam, initially at 700lbf/in2,550∘F undergoes a polytropic process in a piston-cylinder assembly to a final pressure of 2200lbf/ in. 2 Kinetic and potential energy effects are negligible. Determine the heat transfer, in Btu per Ib of steam, for a polytropic exponent of 1.5, (a) using data from the steam tables. (b) assuming ideal gas behavior.
