4. Ammonia in a closed, rigid container undergoes a constant volume (isochoric) process from 5.0 MPa, 200°C to T = 50°C. a. Sketch the process on a P-v diagram b. Find x2, the quality at state 2. 1.Using the Super Heated Vapor (S.H.V.) table for H₂O, find: a. v, specific volume when P = 1200 kPa and T = 635 °C b. P, pressure when T = 800°C and v = .40000 m³/kg c. T, temperature when P = 1600 kPa and u = 2900 kJ/kg
