- A steam power plant that operates on a reheat Rankine cycle and has a net power output of 80 MW. Steam enters the high-pressure turbine at 12 MPa and 520°C ,And the low-pressure turbine at 1.5 MPa and 450°C. Steam leaves the condenser as a saturated liquid at a pressure of 13 kPa. The isentropic efficiency of the turbine is 80 percent, and that of the pump is 95 percent, negligible the isentropic efficiencies of determine: The thermal efficiency of the cycle: The mass flow rate of the steam: The work ratio : the specific steam consumption:arrow_forwardRequired information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Consider a steam power plant that operates on a reheat Rankine cycle and has a net power output of 80 MW. Steam enters the high-pressure turbine at 10 MPa and 500°C and the low-pressure turbine at 1 MPa and 500°C. Steam leaves the condenser as a saturated liquid at a pressure of 10 kPa. The isentropic efficiency of the turbine is 72 percent and that of the pump is 95 percent. Determine the quality (or temperature, if superheated) of the steam at the turbine exit. Use steam tables. (You must provide an answer before moving on to the next part.) The temperature of the steam at the turbine exit is °C.arrow_forwardConsider an ideal steam regenerative Rankine cycle with two feedwater heaters, one closed and one open. Steam enters the turbine at 10 MPa and 500 C and exhausts to the condenser at 10 kPa. Steam is extracted from the turbine at 0.7 MPa for the closed feedwater heater and 0.3 MPa for the open one. The extracted steam leaves the closed feedwater heater and is subsequently throttled to the open feedwater heater. Show the cycle on a T-s diagram with respect to saturation lines, and using only the data presented in the data tables given below determine a) the fraction for steam leaving the boiler that is extracted at 0.3 MPa z=0.1425 b) the fraction of steam leaving the boiler that is extracted at 0.7 MPa y=0.06213 c) the heat transfer from the condenser per unit mass leaving the boiler q_out=1509 kJ/kg d) the heat transfer to the boiler per unit mass leaving the boiler qin=2677 kJ/kg e) the mass flow rate of steam through the boiler for a net power output of 250 MW m'=214.1 kg/s f) the…arrow_forward
