Compressors, Gas Turbines and Jet Engines As the turbine inlet temperature increases, the thermal efficiency of gas turbine for the optimum pressure ratio Decreases Increases Remain same First increases and then decreases Decreases Increases Remain same First increases and then decreases ANSWER DOWNLOAD EXAMIANS APP
Compressors, Gas Turbines and Jet Engines For a two stage reciprocating compressor, compression from p₁ to p₃ is with perfect intercooling and no pressure losses. If compression in both the cylinders follows the same polytropic process and the atmospheric pressure is pa, then the intermediate pressure p₂ is given by p₂ = p₁. p₃ p₂ = Pa p₃/p₁ P₂ = Pa × p₃/p₁ p₂ = (p₁ + p₃)/2 p₂ = p₁. p₃ p₂ = Pa p₃/p₁ P₂ = Pa × p₃/p₁ p₂ = (p₁ + p₃)/2 ANSWER DOWNLOAD EXAMIANS APP
