Effectiveness NTU method Solution

STEP 0: Pre-Calculation Summary

Formula Used

Effectiveness of Heat Exchanger = Heat Exchanged/(Smaller Value*(Entry Temperature of Hot Fluid-Entry Temperature of Cold Fluid))
ϵ = Q/(C_min*(T_H1-T_C1))
This formula uses 5 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.
Heat Exchanged - (Measured in Watt) - Heat exchanged is the amount of heat transferred between two objects.
Smaller Value - Smaller value of mass flowrate of hot fluid * specific heat of hot fluid and mass flowrate of cold fluid * specific heat of cold fluid.
Entry Temperature of Hot Fluid - (Measured in Kelvin) - Entry temperature of hot fluid is the temperature of the hot fluid at entry.
Entry Temperature of Cold Fluid - (Measured in Kelvin) - Entry temperature of cold fluid is the temperature of the cold fluid at entry.

STEP 1: Convert Input(s) to Base Unit

Heat Exchanged: 1350 Watt --> 1350 Watt No Conversion Required
Smaller Value: 30 --> No Conversion Required
Entry Temperature of Hot Fluid: 60 Kelvin --> 60 Kelvin No Conversion Required
Entry Temperature of Cold Fluid: 10 Kelvin --> 10 Kelvin No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

ϵ = Q/(C_min*(T_H1-T_C1)) --> 1350/(30*(60-10))

Evaluating ... ...

ϵ = 0.9

STEP 3: Convert Result to Output's Unit

0.9 --> No Conversion Required

FINAL ANSWER

0.9 <-- Effectiveness of Heat Exchanger

What is Heat exchanger

A heat exchanger is a system used to transfer heat between two or more fluids. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment. The classic example of a heat exchanger is found in an internal combustion engine in which a circulating fluid known as engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air. Another example is the heat sink, which is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant.
