Question

A liquid-vapor mixture of water with a quality of 0.5 and a pressure of 10bar is expanded in an isobaric process until no liquid is left in the mixture. Then, the system undergoes an isometric process that reduces the pressure to 1bar. The system is taken to the initial state (P=10bar, X=0.5) through a process where pressure and volume follow a linear relationship (P=A\cdot v+B). You are asked to: (a) Sketch the cycle in a P-v diagram. (b) Determine the temperature of the three states in $^\circ$C. (c) Determine the specific volumes of the three states in m$^3$/kg. (d) Determine the specific net work of the cycle in kJ/kg. (e) Determine the efficiency of the cycle.

Then, the system undergoes an isometric process that reduces the pressure to 1bar. The system is taken to the initial state (P=10bar, X=0.5) through a process where pressure and volume follow a linear relationship (P=A·v+B). You are asked to:
(a) Sketch the cycle in a P-v diagram.
(b) Determine the temperature of the three states in ^∘C.
(c) Determine the specific volumes of the three states in m^3/kg.
(d) Determine the specific net work of the cycle in kJ/kg.
(e) Determine the efficiency of the cycle.
