Mechanical Engineering

Rankine cycle operates on boiler pressure 15 MPa and condenserpressure of 30 kPa. Superheated steam enters the high-pressureturbine at 450°C. The high-pressure turbine expands the steam andenters the re-heater at 2.5 MPa. The steam is reheated untiltemperature reaches 450°C before being expanded in low-pressureturbine to condenser pressure of 30 kPa. Assume the isentropicefficiency of the low-pressure and high-pressure turbines are 94%and 89% respectively, and pump is working isentropically. Neglectthe change in kinetic energy, potential energy and pressure dropsin boiler and condenser. The net power produced by the plant is 10MW. Determine the followings: (a) Net heat supplied by boiler (inkJ/kg). [10 Marks] (b) Net heat rejected in condenser (in kJ/kg).[6 Marks] (c) Thermal efficiency of the cycle. [2 Marks] (d) Massflow rate of the cycle (in kg/s). [1 Mark] (e) Thermal efficiencyof the cycle if both turbines replaced with isentropic turbine. [6Marks] (f) T-s diagram of the cycle with respect to the saturationlines. [5 Marks]
