Thermo Question I have a reversible turbine, I am given T1,T2, and P1. I need to find P2 using variable specific heat method. NOT THE CONSTANT SPECIFIC HEAT METHOD.What equation would I use? also, the turbine takes in air. I know I would use steam tables for this part. Please let me know, thank you. ***Note that the constant specific heat method is p2 = p1(T2/T1)^(k/k-1).. I am not talking about this method. Thanks.
