Compressors, Gas Turbines and Jet Engines A 3 m³/min compressor means that it Compresses 3 m³/ min of free air Compresses 3 m³/min of standard air Delivers 3 m³/ min of compressed air Delivers 3 m³/ min of compressed air at delivery pressure Compresses 3 m³/ min of free air Compresses 3 m³/min of standard air Delivers 3 m³/ min of compressed air Delivers 3 m³/ min of compressed air at delivery pressure ANSWER DOWNLOAD EXAMIANS APP
Compressors, Gas Turbines and Jet Engines The clearance volume of the air compressor is kept minimum because 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 It results in minimum work It greatly affects volumetric efficiency ANSWER DOWNLOAD EXAMIANS APP
Compressors, Gas Turbines and Jet Engines Volumetric efficiency of a compressor without clearance volume May increase/decrease depending on compressor capacity Is not dependent upon compression ratio Decreases with increase in compression ratio Increases with increase in compression ratio May increase/decrease depending on compressor capacity Is not dependent upon compression ratio Decreases with increase in compression ratio Increases with increase in compression ratio ANSWER DOWNLOAD EXAMIANS APP
