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 = Pa p₃/p₁ p₂ = (p₁ + p₃)/2 p₂ = p₁. p₃ P₂ = Pa × p₃/p₁ p₂ = Pa p₃/p₁ p₂ = (p₁ + p₃)/2 p₂ = p₁. p₃ P₂ = Pa × p₃/p₁ ANSWER DOWNLOAD EXAMIANS APP
Compressors, Gas Turbines and Jet Engines The efficiency of the vane blower is (where W₁ = Workdone due to compression, and W₂ = Workdone due to back flow) (W₁ + W₂)/W₂ W₁/(W₁ + W₂) (W₁ + W₂)/W₁ W₂/(W₁ + W₂) (W₁ + W₂)/W₂ W₁/(W₁ + W₂) (W₁ + W₂)/W₁ W₂/(W₁ + W₂) ANSWER DOWNLOAD EXAMIANS APP
