Water in a piston-cylinder assembly, initially at a temperature of 99.59 °C and a quality of 52%, is heated at constant pressure to a temperature of 210 °C. Changes in kinetic and potential energy are negligible. If the work during the process is +300 kJ,
(a) Determine the phase of the final state. Plot the process on T-υ and P-υ diagrams.
(b) Find initial pressure P1, initial specific volume υ1, initial specific internal energy u1; and final P2, υ2 and u2. Show the process of interpolation where interpolation is needed.
(c) The total mass of water (liquid and vapor) in kg.
(d) The heat transfer in kJ.
