Suction Pressure given Compression Ratio Solution

STEP 0: Pre-Calculation Summary
Formula Used
Suction pressure = Discharge Pressure of Refrigerant/Compression Ratio
P1 = P2/r
This formula uses 3 Variables
Variables Used
Suction pressure - (Measured in Pascal) - The Suction Pressure is the pressure of the refrigerant before the compression. It is also called the suction pressure of the refrigerant.
Discharge Pressure of Refrigerant - (Measured in Pascal) - The discharge pressure of refrigerant is the pressure of the refrigerant after the compression stage or it is the pressure of the refrigerant at the discharge.
Compression Ratio - Compression ratio is the ratio of the absolute stage discharge pressure to the absolute stage suction pressure.
STEP 1: Convert Input(s) to Base Unit
Discharge Pressure of Refrigerant: 8 Bar --> 800000 Pascal (Check conversion here)
Compression Ratio: 4.75 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
P1 = P2/r --> 800000/4.75
Evaluating ... ...
P1 = 168421.052631579
STEP 3: Convert Result to Output's Unit
168421.052631579 Pascal -->1.68421052631579 Bar (Check conversion here)
FINAL ANSWER
1.68421052631579 1.684211 Bar <-- Suction pressure

Which compression ratio is best?

Compression ratios usually vary between 1.05 - 7 per stage; however, a ratio of 3.5 - 4.0 per stage is considered the maximum for most process operations. Quite often, the temperature rise of the gas during the compression dictates a limit for the safe or reasonable pressure rise.
