Area of heat exchanger Solution

STEP 0: Pre-Calculation Summary

Formula Used

Area = Heat exchanged/(Overall Heat Transfer Coefficient*Logarithmic Mean Temperature Difference*Correction Factor)
A = Q/(U*ΔT_m*f)
This formula uses 5 Variables

Variables Used

Area - (Measured in Square Meter) - The area is the amount of two-dimensional space taken up by an object.
Heat exchanged - (Measured in Watt) - Heat exchanged is the amount of heat transferred between two objects.
Overall Heat Transfer Coefficient - (Measured in Watt per Square Meter per Kelvin) - Overall heat transfer coefficient is the overall convective heat transfer between a fluid medium (a fluid) and the surface (wall) flowed over by the fluid.
Logarithmic Mean Temperature Difference - Logarithmic Mean Temperature Difference is the log of the mean of the temperature values.
Correction Factor - Correction Factor is that which is multiplied with the result of an equation to correct for a known amount of systematic error.

STEP 1: Convert Input(s) to Base Unit

Heat exchanged: 50 Watt --> 50 Watt No Conversion Required
Overall Heat Transfer Coefficient: 50 Watt per Square Meter per Kelvin --> 50 Watt per Square Meter per Kelvin No Conversion Required
Logarithmic Mean Temperature Difference: 30 --> No Conversion Required
Correction Factor: 0.5 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A = Q/(U*ΔT_m*f) --> 50/(50*30*0.5)

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.

How to Calculate Area of heat exchanger?

Area of heat exchanger calculator uses Area = Heat exchanged/(Overall Heat Transfer Coefficient*Logarithmic Mean Temperature Difference*Correction Factor) to calculate the Area, The Area of heat exchanger formula is defined as the total area through which the heat exchange takes place. Area is denoted by A symbol.
