Hands$-$On Activity: Thermodynamic Cycle Calculation

A Rankine cycle operates with a reheater to increase efficiency. The cycle involves the following conditions:

Boiler Pressure $($P$\_$boiler$)$: $4$ MPa $(4000$ kPa $)$

Condenser Pressure $($P$\_$condenser$)$: $20$ kPa

First Turbine Stage Outlet Pressure $($Reheat Inlet Pressure$)$: $0\mathrm{.}8$MPa$(800$kPa$)$

Boiler Outlet $($First Turbine Inlet$)$ Temperature $($T$\_$boiler$\_$out$)$: $450C$

Reheater Outlet $($Second Turbine Inlet$)$ Temperature $($T$\_$reheat$\_$out$)$: $400C$

Condenser Outlet $($Pump Inlet$)$ Condition:

Saturated liquid

Objective is to calculate the work done by the pump, the heat added in the boiler and reheater, the work done by the turbine in two stages, the heat rejected in the condenser, and the overall thermal efficiency of the cycle with reheat.

Details:

Step $1$: Define the cycle stages $($e$.$g$.,$ isentropic compression, isobaric heat addition$).$

Step $2$: Provide initial conditions and properties at each stage.

Step $3$: Calculate work and heat transfer for each process using the First Law of Thermodynamics.

Step $4$: Calculate the overall efficiency of the cycle using the Second Law.
