## Compression or Expansion Ratio Solution

STEP 0: Pre-Calculation Summary
Formula Used
compression_or_expansion_ratio = Pressure at the end of Isentropic Compression/Pressure at the start of Isentropic Compression
rp = P2/P1
This formula uses 2 Variables
Variables Used
Pressure at the end of Isentropic Compression - The Pressure at the end of Isentropic Compression is the intermediate pressure in the cycle from where isobaric cooling starts. (Measured in Bar)
Pressure at the start of Isentropic Compression - The Pressure at the start of Isentropic Compression is the pressure at which the cycle starts. (Measured in Bar)
STEP 1: Convert Input(s) to Base Unit
Pressure at the end of Isentropic Compression: 6 Bar --> 600000 Pascal (Check conversion here)
Pressure at the start of Isentropic Compression: 4 Bar --> 400000 Pascal (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
rp = P2/P1 --> 600000/400000
Evaluating ... ...
rp = 1.5
STEP 3: Convert Result to Output's Unit
1.5 --> No Conversion Required
1.5 <-- Compression or Expansion Ratio
(Calculation completed in 00.016 seconds)
