Project 2 - Rankine cycle Simulator
AIM: Rankine cycle simulator
OBJECTIVE:
- Net work output
- Back work ratio
EQUATIONS:
Use the following parameters for the Rankine Cycle
Turbine Inlet temperature (T3) = 400° C
Turbine Inlet Pressure (P3) = 30 bars
Turbine Outlet Pressure (P4) = Condenser Inlet Pressure (P1) = 0.05 bars
CONTENT:
Consider the following process;
- 1-2 : isentropic expansion in turbine
- 2-3 : constant pressure heat rejection in condensor
- 3-4 : isentropic compression in pump
- 4-1 : constant pressure heat addition in boiler
