Compressors, Gas Turbines and Jet Engines The degree of reaction in an axial flow compressor is defined as the ratio of static enthalpy rise in the Stator to static enthalpy rise in the stage Rotor to static enthalpy rise in the stator Stator to static enthalpy rise in the rotor Rotor to static enthalpy rise in the stage Stator to static enthalpy rise in the stage Rotor to static enthalpy rise in the stator Stator to static enthalpy rise in the rotor Rotor to static enthalpy rise in the stage ANSWER DOWNLOAD EXAMIANS APP
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 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 It does not increase pressure much ANSWER DOWNLOAD EXAMIANS APP
