Compressor Discharge Pressure Formula
The following formula is used to calculate the compressor discharge pressure for a given suction pressure and compression ratio.
P_d = P_s * CR
Variables:
- P_d is the compressor discharge pressure
- P_s is the compressor suction pressure
- CR is the compression ratio
To calculate the compressor discharge pressure, multiply the compressor suction pressure by the compression ratio.
What is Compressor Discharge Pressure?
Compressor discharge pressure is the pressure of the gas or air after it has been compressed by the compressor. This pressure is typically higher than the suction pressure, which is the pressure of the gas or air before it enters the compressor. The discharge pressure is a critical parameter in many industrial and mechanical applications, as it determines the efficiency and performance of the compressor system. It is influenced by factors such as the type of compressor, the compression ratio, and the properties of the gas being compressed.
How to Calculate Compressor Discharge Pressure?
The following steps outline how to calculate the Compressor Discharge Pressure.
- First, determine the compressor suction pressure (P_s).
- Next, determine the compression ratio (CR).
- Finally, calculate the compressor discharge pressure using the formula P_d = P_s * CR.
- After inserting the values and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
