This formula uses 4 Variables
Variables Used
Isentropic Efficiency of Compressor - Isentropic Efficiency of Compressor is the ratio of isentropic work of compressor to actual work of compressor.
Temperature at Compressor Exit - (Measured in Kelvin) - Temperature at Compressor Exit is the temperature of the gases exiting the compressor.
Temperature at Compressor Inlet - (Measured in Kelvin) - Temperature at Compressor Inlet is the temperature of the gases entering the compressor.
Actual Temperature at Compressor Exit - (Measured in Kelvin) - Actual Temperature at Compressor Exit is the temperature of the gases exiting the compressor considering the losses throughout the compression process.
STEP 1: Convert Input(s) to Base Unit
Temperature at Compressor Exit: 420 Kelvin --> 420 Kelvin No Conversion Required
Temperature at Compressor Inlet: 298.15 Kelvin --> 298.15 Kelvin No Conversion Required
Actual Temperature at Compressor Exit: 430 Kelvin --> 430 Kelvin No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
ηC = (T2-T1)/(T2,actual-T1) --> (420-298.15)/(430-298.15)
Evaluating ... ...
