EXAMPLE 10–1 The Simple Ideal Rankine Cycle Consider a steam power plant operating on the simple ideal Rankine cycle. Steam enters the turbine at 3 MPa and 350°C and is condensed in the condenser at a pressure of 75 kPa. Determine the thermal efficiency of this cycle.
2.4 Problem 4: 12.97 Consider an ideal air-standard Stirling cycle with an idealregenerator. The minimum pressure and tmeperature in the cycle are 100 kPa, 25 C, the compression ratio is 11, and the maximum temperature in the cycle is 1000 C. Analyze each of the four processes in this cycle for work and heat transfer, and determine the overall perfomance of the engine.

· Web viewProblem set #9. 1) Water is the working fluid in a Carnot vapor power cycle. Saturated liquid enters the boiler at a pressure of 100 bar, and saturated vapor enters the turbine. The condenser pressure is 0.06 bar. Determine (a) the thermal efficiency. (b) the back work ratio. (c)
G.E. Andrews, in Modern Gas Turbine Systems, 2013. 16.1.2 Gas turbine thermal efficiency and turbine entry temperatures. Gas turbine thermal efficiency in simple cycles is limited by the turbine entry temperature and the history of the development of aero and industrial gas turbines can be traced by the year by year increase in turbine entry temperature.
The methodology of the gas turbine eﬃciency calculation 25 (8% in 4c) and the ﬁrst stage of turbine (4% in 5c), the remaining 8% is used for cooling the following turbine stages (6c). The gas turbine outlet temperature is maintained at the level of t4a= 630 C. Depending on the pressure ratio, β, the COT is adjusted to obtain the de-
