stationary in a frictionless piston-cylinder arrangement with 10 kg of water at 10 MPa at a temperature of OC. Heat is given until the temperature is 400 oC at pressure and then heat is withdrawn until the pressure is 300 kPa at constant volume. Since then, heat is given to the fluid at constant pressure until it becomes saturated steam; a) Show the. temperature, pressure, volume, enthalpy and degree of dryness during the phase changes in a table. (15p) b) Show the phase changes in P-v and T-v diagrams. (10p) c) Find the work and heat transfer after the phase changes.
