Required information. The net work output and the thermal efficiency for the Carnot and the simple ideal Rankine cycles with steam as the working fluid are to be calculated and compared. Steam enters the turbine in both cases at 10 MPa as a saturated vapor, and the condenser pressure is 50 kPa. In the Rankine cycle, the condenser exit state is saturated liquid and, in the Carnot cycle, the boiler inlet state is saturated liquid. Draw the T-s diagrams for both cycles.

Regenerative Cycle (Open Feedwater Heater): 4. Steam enters the turbine at 10 MPa and 550 °C with mass flow rate of 10 kg/s and is condensed in the condenser at a pressure of 10 KPa. Some Steam is extracted from the turbine at 0.8 MPa and enters in an open feedwater heater. Determine the amount of steam that is condensed in the condenser.5. 23 percent of the steam is extracted from the turbine. The enthalpy and pressure at point 6 is 3100 KJ/KG and 1.26 MPa respectively. Determine the enthalpy of point 2.6. A Steam exits the boiler at 15 MPa and 550 °C and the pressure at point 1 and point 3 is 12 KPa and 1.3 MPa respectively.

A steam Rankine cycle operates with a condenser temperature of 30°C, and a boiler pressure of 15MPa. The turbine is divided into two stages, a high-pressure turbine, and a low pressure turbine. In between the turbine stages the steam is reheated by the boiler so that the inlet temperature to both turbine stages is the same. The exit pressure of the first turbine stage is 7MPa. The condenser inlet is a saturated vapor and the outlet a saturated liquid. What is the net work of the cycle? What is the thermal efficiency of the cycle?
2. A Rankine cycle is characterized by turbine inlet conditions of 10 MPa and 500°C. The condenser pressure is 6 kPa. The heat transfer to the steam in the boiler occurs at the rate of 7.0 X 100 kW. The cooling water in the condenser increases in temperature from 20⁰ to 30°C. Determine (a) the net power produced; (b) the cooling-water flow rate in kg/s; (c) the cycle thermal efficiency.
