Compression Ratio given Pressure Solution

STEP 0: Pre-Calculation Summary
Formula Used
Compression Ratio = Discharge Pressure of Refrigerant/Suction pressure
r = P2/P1
This formula uses 3 Variables
Variables Used
Compression Ratio - Compression ratio is the ratio of the absolute stage discharge pressure to the absolute stage suction pressure.
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.
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.
STEP 1: Convert Input(s) to Base Unit
Discharge Pressure of Refrigerant: 8 Bar --> 800000 Pascal (Check conversion here)
Suction pressure: 1.013 Bar --> 101300 Pascal (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
r = P2/P1 --> 800000/101300
Evaluating ... ...
r = 7.89733464955578
STEP 3: Convert Result to Output's Unit
7.89733464955578 --> No Conversion Required
FINAL ANSWER
7.89733464955578 7.897335 <-- Compression Ratio
