Thermodynamics question Consider a steam power plant operating on the simple ideal Rankine cycle. Steam enters the turbine at 3 MPa and 350 °C and is condensed in the condenser at a pressure of 10 kPa. If line number 1 is saturated liquid and assuming 100% isentropic efficiency of the turbine and the pump. Determine: A-work produced in the turbine per unit mass, B-The thermal efficiency of this cycle, C-The heat lost from the condenser, D-maximum possible efficiency of the cycle
