Problem 1: Water at 0.3 MPa and 400°C is placed into a rigid wall container. It is allowed to cool to the ambient temperature of 25°C. Determine a. the required heat transfer in kJ/kg b. the final fluid state (pressure and phase)

Problem 2: Hydrogen gas at 1800K and 1.2 MPa enter a turbine and exhausts at 169.45 kPa. Determine a. the shat work in kJ/kg b. the mass flow rate required to produce a power output of 25 kW.

Problem 3: (This problem will require interpolation!) Refrigerant-12 enters a diffuser at 200 kPa and 20° C with a velocity of 120 m/s. The inlet flow area is 10 cm 2. The exit pressure is 250 kPa and the exit velocity is nonzero. Determine: a. the exit temperature b. the exit velocity c. the mass flow rate through the diffuser
