WebbThus, even though the efficiency (which is not much dependent on the firing temperature) would peak at pressure ratios of about 30 : 1, typical simple-cycle gas-turbine power plants have pressure ratios of between 10 : 1 and 18 : 1, thus optimizing the power out. WebbA gas-turbine power plant operating on an ideal Brayton cycle has a pressure ratio of 8. The gas temperature is 300 K at the compressor inlet and 1300 K at the turbine inlet. Utilizing the air-standard assumptions and by accounting for the variation of specific heats with temperature, determine the thermal efficiency. dwlr6 illuminated reticle https://chansonlaurentides.com
