Problem 4 Part B Air and water flow through the devices below. The air, flowing at 300 kg/s, enters the heat exchanger at 850 K, 1 bar. The water, flowing at 50 kg/s, enters the heat exchanger as a compressed liquid at 10 MPa, 140 °C. The water enters the turbine at 520 °C and exits the turbine at 1.5 MPa. The turbine operates with an isentropic efficiency of 70%.   Assumptions to follow: Constant specific heats for ideal gases Entropy approximation range: ± 0.01 kJ/kg-K   Determine the temperature of the air exiting the heat exchanger (K)
