Determination of heat transfer coefficient
Thread Content
In the design and calculation of heat exchangers, the heat transfer coefficient is usually obtained by consulting tables or through empirical estimates. Is there any way to measure it directly? That would be a more convenient and relatively accurate method. Those who know about this could please explain it. Thank you.
K can be calculated by measuring just 7 values: 1) 4 temperatures: 2 inlet temperatures and 2 outlet temperatures; 2) 2 flow rates; 3) 1 area (the external surface area of the heat exchange tube)
I also want to know how to calculate the heat transfer coefficient
