Capacity Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Heat capacity ratio = Minimum heat capacity/Maximum heat capacity
C = C_min/C_max
This formula uses 3 Variables

Variables Used

Heat capacity ratio - Heat capacity ratio is the ratio of cmin and cmax.
Minimum heat capacity - (Measured in Joule per Kelvin) - Minimum heat capacity is the heat capacity of the fluid in the heat exchanger having a lower value as compared to another fluid.
Maximum heat capacity - (Measured in Joule per Kelvin) - Maximum heat capacity is the heat capacity of the fluid in the heat exchanger having a higher value as compared to another fluid.

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 = C_min/C_max --> 4/8

Evaluating ... ...

C = 0.5

STEP 3: Convert Result to Output's Unit

0.5 --> No Conversion Required

FINAL ANSWER

0.5 <-- Heat capacity ratio

Mass flow rate of cold fluid

Go Mass Flow Rate of Cold Fluid = (Effectiveness of Heat Exchanger*Smaller Value/Specific heat of cold fluid)*(1/((Exit Temperature of Cold Fluid-Entry Temperature of Cold Fluid)/(Entry Temperature of Hot Fluid-Entry Temperature of Cold Fluid)))

Mass flow rate of hot fluid

Go Mass Flow Rate of Hot Fluid = (Effectiveness of Heat Exchanger*Smaller Value/Specific heat of hot fluid)*(1/((Entry Temperature of Hot Fluid-Exit Temperature of Cold Fluid)/(Entry Temperature of Hot Fluid-Entry Temperature of Cold Fluid)))

Correction factor in heat exchanger

Go Correction Factor = Heat exchanged/(Overall Heat Transfer Coefficient*Area*Logarithmic Mean Temperature Difference)

Area of heat exchanger

Go Area = Heat exchanged/(Overall Heat Transfer Coefficient*Logarithmic Mean Temperature Difference*Correction Factor)

Capacity Ratio Formula

Heat capacity ratio = Minimum heat capacity/Maximum heat capacity
C = C_min/C_max

What is Capacity Ratio?

Capacity Ratio is defined as the ratio of minimum to the maximum capacity rate of fluids being used in a heat exchanger. The fluid with a lower heat capacity rate will undergo a greater change in temperature as compared to fluid with a higher heat capacity rate.

How to Calculate Capacity Ratio?

Capacity Ratio calculator uses Heat capacity ratio = Minimum heat capacity/Maximum heat capacity to calculate the Heat capacity ratio, Capacity Ratio formula calculates the capacity ratio of a heat exchanger by the ratio of minimum to maximum heat capacities of the fluids. Heat capacity ratio is denoted by C symbol.

How to calculate Capacity Ratio using this online calculator? To use this online calculator for Capacity Ratio, enter Minimum heat capacity (C_min) & Maximum heat capacity (C_max) and hit the calculate button. Here is how the Capacity Ratio calculation can be explained with given input values -> 0.5 = 4/8.

FAQ

What is Capacity Ratio?

Capacity Ratio formula calculates the capacity ratio of a heat exchanger by the ratio of minimum to maximum heat capacities of the fluids and is represented as C = C_min/C_max or Heat capacity ratio = Minimum heat capacity/Maximum 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 & Maximum heat capacity is the heat capacity of the fluid in the heat exchanger having a higher value as compared to another fluid.

How to calculate Capacity Ratio?

Capacity Ratio formula calculates the capacity ratio of a heat exchanger by the ratio of minimum to maximum heat capacities of the fluids is calculated using Heat capacity ratio = Minimum heat capacity/Maximum heat capacity. To calculate Capacity Ratio, you need Minimum heat capacity (C_min) & Maximum heat capacity (C_max). With our tool, you need to enter the respective value for Minimum heat capacity & Maximum heat capacity and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
