(i) A piston cylinder assembly contains a two-phase
liquid-vapour mixture of water at 40 bar with a quality of 80%. The
mixture is heated and expands at a constant pressure until a final
temperature of 320 degrees C is reached. (State all formulas)
(i) Determine the work for the process in kJ per kg of
water.
(ii) Determine the heat transfer in kJ per kg of water.
(iii) Show the process on a sketch of a T-v diagram, include all
key features.
