Question

Super heated vapor enters the turbine at 10 MPa, 480°C, and the condenser pressure is 7.5 kPa of a steam Rankine power cycle. Isentropic efficiencies of the turbine and pump

are 84% and 73%,respectively. Determine for the cycle a.Sketch the cycle of a T-s diagram. Indicate the isobars with their values and the values for temperature and entropy. The heat transfer to the working fluid passing through the steam generator, in kJ per kg of steam flowing.b. The thermal efficiency.с. d. Compute the entropy generated by the turbine per unit of mas of steam flowing. The heat transfer from the working fluid passing through the condenser to the cooling water, inkJ per kg of steam flowing. [Hint: this refers to the cooling tower]е.
