Heat Exchanger Effectiveness Solution

STEP 0: Pre-Calculation Summary

Formula Used

Effectiveness of Heat Exchanger = Actual Rate of Heat Transfer/Maximum Possible Rate of Heat Transfer
ϵ = Q_Actual/Q_Max
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.
Actual Rate of Heat Transfer - (Measured in Joule per Second) - Actual Rate of Heat Transfer is the amount of heat that is transferred per unit of time in some material.
Maximum Possible Rate of Heat Transfer - (Measured in Joule per Second) - Maximum Possible Rate of Heat Transfer is defined as the maximum amount of heat that is transferred per unit of time in some material.

STEP 1: Convert Input(s) to Base Unit

Actual Rate of Heat Transfer: 999 Joule per Second --> 999 Joule per Second No Conversion Required
Maximum Possible Rate of Heat Transfer: 60000 Joule per Second --> 60000 Joule per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

ϵ = Q_Actual/Q_Max --> 999/60000

Evaluating ... ...

ϵ = 0.01665

STEP 3: Convert Result to Output's Unit

0.01665 --> No Conversion Required

FINAL ANSWER

0.01665 <-- Effectiveness of Heat Exchanger
