Compressor Characteristic - Wikipedia
Compressor characteristic is the curve to show the behaviour of fluid, like change in pressure, temperature, entropy, flow rate etc. as it passes through a Dynamic compressor at different compressor speeds. The function of a compressor is to increase the pressure of a fluid passing through it, so that the exit pressure is higher than the inlet pressure. ... Get Content Here
A Method To Estimate The Performance Of Reciprocating Compressors
The warm up coefficient αdepends on the way the compressor is cooled. As starting proposal, the coefficient can be put at 1 if the compressor is static and 0.95 if the compressor is fan. The coefficient of performance can be estimated as the ratio of the cooling capacity to the power input. The power input to a compressor can be expressed as: ... Read Document
