Compressors, Gas Turbines and Jet Engines If the flow of air through the compressor is parallel to its axis, then the compressor is Turbo compressor Reciprocating compressor Centrifugal compressor Axial flow compressor Turbo compressor Reciprocating compressor Centrifugal compressor Axial flow compressor ANSWER DOWNLOAD EXAMIANS APP
Compressors, Gas Turbines and Jet Engines The clearance volume of the air compressor is kept minimum because It results in minimum work It greatly affects volumetric efficiency It allows maximum compression to be achieved It permits isothermal compression It results in minimum work It greatly affects volumetric efficiency It allows maximum compression to be achieved It permits isothermal compression ANSWER DOWNLOAD EXAMIANS APP
Compressors, Gas Turbines and Jet Engines Isothermal compression though most efficient, but is not practicable because 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 It requires very big cylinder ANSWER DOWNLOAD EXAMIANS APP
