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 Logarithmic mean temperature difference?
Logarithmic mean temperature difference calculator uses Logarithmic Mean Temperature Difference = Heat exchanged/(Correction Factor*Overall Heat Transfer Coefficient*Area) to calculate the Logarithmic Mean Temperature Difference, The Logarithmic mean temperature difference formula is defined as the log of the mean difference of the temperature values. Logarithmic Mean Temperature Difference is denoted by ΔTm symbol.
How to calculate Logarithmic mean temperature difference using this online calculator? To use this online calculator for Logarithmic mean temperature difference, enter Heat exchanged (Q), Correction Factor (f), Overall Heat Transfer Coefficient (U) & Area (A) and hit the calculate button. Here is how the Logarithmic mean temperature difference calculation can be explained with given input values -> 0.04 = 50/(0.5*50*50).
