1. Below is a schematic diagram of a simple steam power plant. Steam is heated inside an isobaric boiler and enters the turbine at 1 MPa and 300°C. It exits the turbine at 500 kPa, saturated vapor. The steam is then cooled down to saturated liquid at 500 kPa by cooling water flowing in at 35 °C and out at 85 °C of the condenser. The needed power of the pump is 11.071 MW. The steam is pumped into a throttling device back to the boiler.The mass flow rate of steam circulating the condenser is 100 kg/s. Determine the following: a. Turbine work in MW b. Heat rejected from the condenser in MW c. Mass flow rate of cooling water in kg/s d. Inlet boiler temperature in °C e. Heat added in the boiler in MW Qboiler 5 Isobaric Boiler P1= 1MPA T1= 300°C Wpump=11.071 MW Wturbine Condenser 3 P2= 500 kPa P2= 500 kPa Saturated Saturated Liquid Vapor T2,cw = 85°C T1,cw = 35°C %3D Qcondenser m2 =100 kg/s Turbine Pump
