a cyclic steam power plant is to be designed for a steam temperature at turbine inlet of 360 celsius and an exhaust pressure of 0.08bar. after an isentropic expansion of steam in the turbine, the moisture content at the turbine exhaust is not to exceed 15%. determine the greatest allowable steam pressure at the turbine inlet and calculate the cycle efficiency.
Calculate the net cycle work in kJ assuming air is an ideal gas with constant specific heats.
The Brayton cycle shown in figure 6.41 operates using CO2 as a working fluid with compressor and turbine isentropic efficiencies of 1.0. Calculate the thermal efficiency of this cycle when the working fluid is modeled.
