Compressors, Gas Turbines and Jet Engines Isothermal compression though most efficient, but is not practicable because It does not increase pressure much It requires very big cylinder It is impossible in practice Compressor has to run at very slow speed to achieve it It does not increase pressure much It requires very big cylinder It is impossible in practice Compressor has to run at very slow speed to achieve it 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) W₂/(W₁ + W₂) (W₁ + W₂)/W₂ (W₁ + W₂)/W₁ W₁/(W₁ + W₂) W₂/(W₁ + W₂) (W₁ + W₂)/W₂ (W₁ + W₂)/W₁ W₁/(W₁ + W₂) ANSWER DOWNLOAD EXAMIANS APP
