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.

Thermo one Question 5 A steam turbine generates energy in the form of work at the rate of 346.1 kJ/kg of steam. The steam at the inlet of the turbine is at 8 MPa, 480oC, and at a velocity of 163.5 m/s. The steam exits the turbine at 2 MPa, 240oC, and a velocity of 55.3 m/s. Heat transfer to the surroundings occurs where the outer surface (boundary) temperature is at 333.5oC. Determine the rate of entropy production (kJ/kg-K) within...

Problem 6.055 SI Water at P1 = 20 bar, T1 = 400°C enters a turbine operating at steady state and exits at P2 = 1.5 bar, T2 = 230°C. The water mass flow rate is 4000 kg/hour. Stray heat transfer and kinetic and potential energy effects are negligible. Determine the power produced by the turbine, in kW, and the rate of entropy production in the turbine, in kW/K. Step 1 Determine the power produced by the turbine, in kW. W,...

2 moles of compressed air (diatomic gas) in a cylinder under the initial condition T1=573K p1=500kPa. Found v1=0.019m^3 but can not remember then how to find V2. I think that it has something to do with T1=T2 condition then P2 can be found.... but stuck on how to proceed so with FULL written explanations with working would be much appreciated!
