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
