#$1.$ Steam at $8$ MPa and $480$C enters the first$-$stage turbine of a real Rankine cycle

with reheat and expands to $0\mathrm{.}7$ MPa. The steam leaving the reheat section of the

steam generator $($boiler$)$ is at $440$C$,$ and the condenser pressure is $8$ kPa.

Assuming isentropic efficiency of $85\%$ for turbines and pump, determine:

a$.$ Find specific enthalpy and specific entropy at all states of the cycle.

b$.$ Total power developed by both turbines, in kJ$/$kg$.$

c$.$ Power consumed by the pump, in kJ$/$kg$.$

d$.$ Rate of heat transfer to the steam passing through the boiler, in kJ$/$kg$.$

e$.$ Draw T$-$s diagram for the cycle.
