Steam at 6.155MPa and 435degC enters the turbine of a power plant which operates on actual vaport power cycle. The pressure at the exit of the turbine is 418 kPa, and steam leaves the condenser as a saturated liquid at 62degC. The pressure is increased to 12.2 MPa accross the pump. The turbine and pump have isentropic efficiencies of 82% and 74% respectively.  For this cycle, determine th: a. Wnet per unit mass of steam flow and the heat transfer to steam passing through the boiler (kj/kg) b. thermal efficiency (%) c. heat transfer to colling water passing the condenser (kj/kg of steam condensed)

Steam at 6.155MPa and 435degC enters the turbine of a power plant which operates on actual vaport power cycle. The pressure at the exit of the turbine is 418 kPa, and steam leaves the condenser as a saturated liquid at 62degC. The pressure is increased to 12.2 MPa accross the pump. The turbine and pump have isentropic efficiencies of 82% and 74% respectively. 

For this cycle, determine th:

a. Wnet per unit mass of steam flow and the heat transfer to steam passing through the boiler (kj/kg)
b. thermal efficiency (%)

c. heat transfer to colling water passing the condenser (kj/kg of steam condensed)
