111) For a multi-stage compressor, the polytropic efficiency is constant throughout for all the stages.

112) In a high pressure compressor, the delivery pressure is

113) When the outlet angle from the rotor of a centrifugal compressor is more than 90 Degree, then the blades are said to be

114) In axial flow compressors, the flow of air is parallel to the axis of compressor.

115) The ratio of the isothermal power to the shaft power or brake power of the motor or engine required to drive the compressor is called overall isothermal efficiency.
