Compressors, Gas Turbines and Jet Engines Isothermal compression though most efficient, but is not practicable because It requires very big cylinder It is impossible in practice It does not increase pressure much Compressor has to run at very slow speed to achieve it It requires very big cylinder It is impossible in practice It does not increase pressure much Compressor has to run at very slow speed to achieve it ANSWER DOWNLOAD EXAMIANS APP
