An ideal Rankine cycle operates between the pressure limits of 6 bar and 0.1 bar with steam as the working fluid (data above). Saturated water leaves the condenser and the turbine inlet temperature is 250°C. You may assume that the work input to the boiler feed water pump is negligible. Estimate the efficiency of the cycle and determine the turbine power in kJ/kg.
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?
Water is the working fluid in a Rankine cycle. Steam exits the steam generator at 1500 lbf/in.2 and 1100°F. Due to heat transfer and frictional effects in the line connecting the steam generator and turbine, the pressure and temperature at the turbine inlet are reduced to 1400 lbf/in.² and 1000°F, respectively. Both the turbine and pump have isentropic efficiencies of 95%. Pressure at the condenser inlet is 2 lbf/ in.2, but due to frictional effects the condensate exits the condenser at a pressure of 1.5 lbf/in.² and a temperature of 110°F.
