QUESTION 4 Determine the final pressure (kPa) for a gas undergoing a process from state 1 (T1 = 300 K, P1 = 129 kPa) to a temperature of T2 = 839 K if s2 - s1 = 0.903 kJ/kg-K. Assume constant specific heats as given below (DO NOT USE the ideal gas tables). Cp = 1.135 kJ/kg-K Cv = 0.759 kJ/kg-K
Air goes through a polytropic process in a piston/cylinder setup. The polytropic index is n. The process starts at P1 kPa, T1 oC, and ends with a pressure of P2 kPa. Answer Questions 6-8 about this process, considering the given information in Question 6. Assume air to be an ideal gas. Let, n=1.5 P1=2.3 MPa T1= 8.9 ×102 °C P2=2.1 ×102 kPa Cp = 1.004 kJ/kg-K, Cv = 0.717 kJ/kg-K, R = 0.287 kJ/kg-K Find the final temperature, in oC...

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.
Air flows through a converging-diverging nozzle/diffuser. Assuming isentropic flow, air as an ideal gas, and constant specific heats determine the state at several locations in the system. Note: The specific heat ratio and gas constant for air are given as k=1.4 and R=0.287 kJ/kg-K respectively. --Given Values-- Inlet Temperature: T1 (K) = 360 Inlet pressure: P1 (kPa) = 583 Inlet Velocity: V1 (m/s) = 105 Area at inlet (cm^2) = 8.2 Mach number at the exit = 1.86 a) Determine...
