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 p₂ = (p₁ + p₃)/2 P₂ = Pa × p₃/p₁ p₂ = Pa p₃/p₁ p₂ = p₁. p₃ p₂ = (p₁ + p₃)/2 P₂ = Pa × p₃/p₁ ANSWER DOWNLOAD EXAMIANS APP
Compressors, Gas Turbines and Jet Engines Isothermal compression though most efficient, but is not practicable because Compressor has to run at very slow speed to achieve it It requires very big cylinder It does not increase pressure much It is impossible in practice Compressor has to run at very slow speed to achieve it It requires very big cylinder It does not increase pressure much It is impossible in practice ANSWER DOWNLOAD EXAMIANS APP
