Heat Exchanger Effectiveness for Minimum Fluid Solution

STEP 0: Pre-Calculation Summary

Formula Used

Effectiveness of Heat Exchanger = Temperature Difference of Minimum Fluid/Maximum Temperature Difference in Heat Exchanger
ϵ = ΔT_{Min Fluid}/ΔT_{Max HE}
This formula uses 3 Variables

Variables Used

Effectiveness of Heat Exchanger - The effectiveness of heat exchanger is defined as the ratio of the actual heat transfer to the maximum possible heat transfer.
Temperature Difference of Minimum Fluid - (Measured in Kelvin) - Temperature Difference of Minimum Fluid is defined as the difference of outlet temperature and inlet temperature or vice versa of minimum fluid. Minimum Fluid can be hot or cold fluid.
Maximum Temperature Difference in Heat Exchanger - (Measured in Kelvin) - Maximum Temperature Difference in Heat Exchanger is defined as temperature difference between the hot and cold fluid in heat exchanger.

STEP 1: Convert Input(s) to Base Unit

Temperature Difference of Minimum Fluid: 290 Kelvin --> 290 Kelvin No Conversion Required
Maximum Temperature Difference in Heat Exchanger: 320 Kelvin --> 320 Kelvin No Conversion Required

STEP 2: Evaluate Formula

Effectiveness of Counter-Current Heat Exchanger if Cold Fluid is Minimum Fluid

Go Effectiveness of HE when Cold Fluid is Min Fluid = (modulus((Inlet Temperature of Cold Fluid-Outlet Temperature of Cold Fluid))/(Inlet Temperature of Hot Fluid-Outlet Temperature of Cold Fluid))

Effectiveness of Parallel-Flow Heat Exchanger if Cold Fluid is Minimum Fluid

Go Effectiveness of HE when Cold Fluid is Min Fluid = (Outlet Temperature of Cold Fluid-Inlet Temperature of Cold Fluid)/(Inlet Temperature of Hot Fluid-Inlet Temperature of Cold Fluid)

Effectiveness of Parallel-Flow Heat Exchanger if Hot Fluid is Minimum Fluid

Go Effectiveness of HE when Hot Fluid is Min Fluid = ((Inlet Temperature of Hot Fluid-Outlet Temperature of Hot Fluid)/(Inlet Temperature of Hot Fluid-Inlet Temperature of Cold Fluid))

Effectiveness of Counter-Current Heat Exchanger if Hot Fluid is Minimum Fluid

Go Effectiveness of HE when Hot Fluid is Min Fluid = (Inlet Temperature of Hot Fluid-Outlet Temperature of Hot Fluid)/(Inlet Temperature of Hot Fluid-Outlet Temperature of Cold Fluid)

Heat Exchanger Effectiveness for Minimum Fluid

Go Effectiveness of Heat Exchanger = Temperature Difference of Minimum Fluid/Maximum Temperature Difference in Heat Exchanger

Heat Exchanger Effectiveness

Go Effectiveness of Heat Exchanger = Actual Rate of Heat Transfer/Maximum Possible Rate of Heat Transfer
