2) Consider a Rankine cycle in which the steam at 10.0 MPa and 500C enters the turbine and saturated liquid at 20 kPa leaves the condenser. The isentropic efficiencies of the turbine and pump are 0.85 and 0.9 respectively. Determine the thermal efficiency of this Rankine cycle. 3) Repeat problem 2 but assume that the pressure at the condenser is 10 kPa. 4) Repeat problem 2 but assume steam enters the turbine at 10.0 MPa and 700C. 5) Repeat problem 2 but assume steam enters the turbine at 15.0 MPa and 500C.
