1. Steam is the working fluid in a Rankine cycle. Saturated vapor enters the turbine at 8.0 MPa and saturated liquid exits the condenser at a pressure of 0.008 MPa. The net power output of the cycle is 100 MW. Determine for the cycle: (a) thermal efficiency (b) back work ratio (c) mass flow rate of steam in kg/hr (d) rate of heat transfer into the working fluid in the boiler (e) rate of heat transfer from the condensing steam as it passes through the condenser (f) mass flow rate of cooling water if the cooling water enters at 15°C and exits at 35°C. Assume the isentropic efficiency of the pump and the turbine to be 85%.
