Compressors, Gas Turbines and Jet Engines Volumetric efficiency is The ratio of stroke volume to clearance volume Reciprocal of compression ratio The ratio of the air actually delivered to the amount of piston displacement Index of compressor performance The ratio of stroke volume to clearance volume Reciprocal of compression ratio The ratio of the air actually delivered to the amount of piston displacement Index of compressor performance 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 = 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
