Consider a closed system undergoing a power cycle using water as the working

substance. The cycle comprises of three sequential processes.

Process from State $1$ to State $2$: polytropic process with a polytropic index of $0\mathrm{.}74$

Process from State $2$ to State $3$: Isobaric process

Process from State $3$ to State $1$: isochoric process

The following data is given:

Pressure at State $1$: $15$ bar

Quality at State $1$: $,1\mathrm{.}0$

Pressure at State $2$: $10$ bar

Ignoring the effects of kinetic and gravitational potential energles, answer the

following:

a$)$ Complete the following Table $(18$ points$)$:

b$)$ Neatly sketch the power cycle on $p-v$ and $T-v$ diagrams. Use a separate

and the entire page to draw these diagrams. $(15$ points$).$
