STEP 1: Convert Input(s) to Base Unit

Convection coefficient based on inside area: 2 Watt per Square Meter per Kelvin --> 2 Watt per Square Meter per Kelvin No Conversion Required
Inner Diameter: 35 Meter --> 35 Meter No Conversion Required
Height of Crack: 12000 Millimeter --> 12 Meter (Check conversion here)
Effective convection coefficient on outside: 14 Watt per Square Meter per Kelvin --> 14 Watt per Square Meter per Kelvin No Conversion Required
Fin Efficiency: 0.54 --> No Conversion Required
Surface Area: 0.52 Square Meter --> 0.52 Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

AB = ((h_ia*pi*d_i*h_c)/(h_oe))-(η*A_s) --> ((2*pi*35*12)/(14))-(0.54*0.52)

Evaluating ... ...

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.
