Air in a piston$/$cylinder device undergoes a continuous cycle as shown here: from State $1$ to State $2$ to State $3$ to State $1$ to State $2,$ etc... The air cycles between two pressures $160$

kPa and $390$ kPa and two specific volumes. The first process in the cycle $(1-2)$ is an isothermal process at $350$ K $.$ Assuming that air can be treated as an ideal gas, determine the

following.

$\frac{m^3}{(kg)}$

$\frac{kJ}{kg}$

e$)$ the boundary work for Process $3($State $3$ to State $1)$

$\frac{kJ}{kg}$

f$)$ total work done on the air for each complete cycle $($BE CAREFUL. You are asked for the work done on the air, not by the air.$)$
