Tube inside area required for heat exchange Solution

STEP 0: Pre-Calculation Summary

Formula Used

Area = Heat Flow Rate/(Overall Heat Transfer Coefficient*Logarithmic Mean Temperature Difference)
A = Q/(U_overall*ΔT_m)
This formula uses 4 Variables

Variables Used

Area - (Measured in Square Meter) - The area is the amount of two-dimensional space taken up by an object.
Heat Flow Rate - (Measured in Watt) - Heat Flow Rate is the amount of heat that is transferred per unit of time in some material, usually measured in watt. Heat is the flow of thermal energy driven by thermal non-equilibrium.
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.

STEP 1: Convert Input(s) to Base Unit

Heat Flow Rate: 125 Watt --> 125 Watt No Conversion Required
Overall Heat Transfer Coefficient: 0.25 Watt per Square Meter per Kelvin --> 0.25 Watt per Square Meter per Kelvin No Conversion Required
Logarithmic Mean Temperature Difference: 30 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A = Q/(U_overall*ΔT_m) --> 125/(0.25*30)

Evaluating ... ...

A = 16.6666666666667

STEP 3: Convert Result to Output's Unit

16.6666666666667 Square Meter --> No Conversion Required

FINAL ANSWER

16.6666666666667 ≈ 16.66667 Square Meter <-- Area

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.
