## Capacity Ratio Solution

STEP 0: Pre-Calculation Summary
Formula Used
heat_capacity_ratio = Minimum heat capacity/Maximum heat capacity
C = Cmin/Cmax
This formula uses 2 Variables
Variables Used
Minimum heat capacity - Minimum heat capacity is the heat capacity of the fluid in the heat exchanger having a lower value as compared to another fluid. (Measured in Joule per Kelvin)
Maximum heat capacity - Maximum heat capacity is the heat capacity of the fluid in the heat exchanger having a higher value as compared to another fluid. (Measured in Joule per Kelvin)
STEP 1: Convert Input(s) to Base Unit
Minimum heat capacity: 4 Joule per Kelvin --> 4 Joule per Kelvin No Conversion Required
Maximum heat capacity: 8 Joule per Kelvin --> 8 Joule per Kelvin No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
C = Cmin/Cmax --> 4/8
Evaluating ... ...
C = 0.5
STEP 3: Convert Result to Output's Unit
0.5 --> No Conversion Required
0.5 <-- Heat capacity ratio
