An ideal regenerative Rankine cycle (steam power plant) has two open feedwater heaters. The rejected heat from the plant to the atmosphere is found to be 50 MW. Steam enters the turbine at 12.5 MPa and 600°C and exhausts to the condenser at 10 kPa. Steam is extracted from the turbine at 0.6 and 0.3 MPa. Water leaves both feedwater heaters as a saturated liquid. Show the cycle on a T-s diagram, and determine (a) the net power output of the power plant in MW and (b) the thermal efficiency of the cycle.

Consider a 210-MW steam power plant that operates on a simple ideal Rankine cycle. Steam enters the turbine at 10 MPa and 500°C and is cooled in the condenser at a pressure of 7.5 kPa. Show the cycle on a T-s diagram with respect to saturation lines.
A simple ideal Rankine cycle with water as the working fluid operates between the pressure limits of 3 MPa in the boiler and 30 kPa in the condenser. If the quality at the exit of the turbine cannot be less than 80 percent, what is the maximum thermal efficiency this cycle can have? Use steam tables. The maximum thermal efficiency is %.
Required 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.
An ideal Rankine cycle with one stage of reheat utilizes steam as working medium. Boiler pressure is 4 MPa, the boiler exit temperature is 400°C, and the condenser pressure is 10 kPa. The reheat takes place at 0.4 MPa and the steam leaves the reheater at 400°C. (Enthalpies are in KJ/kg.). Determine the thermal efficiency of the cycle. Determine also the thermal efficiency if there is no reheater. The quality at the exhaust of the low pressure turbine is: Select one: O a. 13% O b. 97% O c. 3% O d. 87%
Consider 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…
