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 Heat transfer surface area for unit length given time factor?
Heat transfer surface area for unit length given time factor calculator uses Surface Area = (Time Factor*Specific heat of matrix material*Mass of Solid)/(Convective Heat Transfer Coefficient*Total Time Taken) to calculate the Surface Area, The Heat transfer surface area for unit length given time factor formula is defined as the area of the surface of the heat exchanger where heat transfer takes place. Surface Area is denoted by SA symbol.
How to calculate Heat transfer surface area for unit length given time factor using this online calculator? To use this online calculator for Heat transfer surface area for unit length given time factor, enter Time Factor (n), Specific heat of matrix material (cs), Mass of Solid (ML), Convective Heat Transfer Coefficient (hConv) & Total Time Taken (ttotal) and hit the calculate button.
