Q$\mathrm{.}5)$ In an adiabatic turbine steam enters steadily at $1\mathrm{.}8$MPa and $550C$ and leaves at $100$kPa. If the isentropic efficiency of the turbine is $61\mathrm{.}2\%$ and mass flow rate is $3k\frac{g}{s},$ draw the process in $P-h$ diagram and determine

a$)$ Enthalpy and entropy of the steam at the inlet

b$)$ Enthalpy of the water at the exit for the case of isentropic expansion $($h$2$s$).$

c$)$ Actual enthalpy, entropy and temperature of the fluid at the exit.

d$)$ Work produced.

e$)$ Plot the effect of the isentropic efficiency on the work output.

f$)$ Solve the problem using organic fluid R$245$fa
