Compression or Expansion Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Compression or Expansion Ratio = Pressure at End of Isentropic Compression/Pressure at Start of Isentropic Compression
r_p = P₂/P₁
This formula uses 3 Variables

Variables Used

Compression or Expansion Ratio - Compression or Expansion Ratio is the ratio of the volume of air before compression or expansion to the volume after compression or expansion in air refrigeration.
Pressure at End of Isentropic Compression - (Measured in Pascal) - Pressure at End of Isentropic Compression is the final pressure achieved at the end of the isentropic compression process in an air refrigeration system.
Pressure at Start of Isentropic Compression - (Measured in Pascal) - Pressure at Start of Isentropic Compression is the initial pressure of the refrigerant at the beginning of the isentropic compression process in an air refrigeration system.

STEP 1: Convert Input(s) to Base Unit

Pressure at End of Isentropic Compression: 10000000 Pascal --> 10000000 Pascal No Conversion Required
Pressure at Start of Isentropic Compression: 400000 Pascal --> 400000 Pascal No Conversion Required

What is Compression or Expansion Ratio?

The Compression or Expansion Ratio refers to the ratio of the volume of air before compression or expansion to its volume after the process. In air refrigeration systems, a higher compression ratio generally leads to a greater temperature increase during compression and a larger temperature drop during expansion. This ratio is crucial in determining the efficiency and performance of the refrigeration cycle.

How to Calculate Compression or Expansion Ratio?

Compression or Expansion Ratio calculator uses Compression or Expansion Ratio = Pressure at End of Isentropic Compression/Pressure at Start of Isentropic Compression to calculate the Compression or Expansion Ratio, Compression or Expansion Ratio formula is defined as the ratio of the discharge pressure to the suction pressure of a refrigerant in a refrigeration system, used to measure the performance of a compressor or an expander in refrigeration and air conditioning systems. Compression or Expansion Ratio is denoted by r_p symbol.

How to calculate Compression or Expansion Ratio using this online calculator? To use this online calculator for Compression or Expansion Ratio, enter Pressure at End of Isentropic Compression (P₂) & Pressure at Start of Isentropic Compression (P₁) and hit the calculate button. Here is how the Compression or Expansion Ratio calculation can be explained with given input values -> 25 = 10000000/400000.

FAQ
