Calculating Rate of Heat Transfer in Parallel Flow Heat Exchangers

engineers.acad...
In this video tutorial, you will learn how to calculate the rate of heat transfer in a parallel flow heat exchanger. You will be shown how to determine the log mean temperature from the fluid inlet and outlet temperatures, before determining the effective rate of heat transfer in Watts.

Correction since the LMTD is in Celcius you must convert it into absolute temperature before you multiply it. Am I wrong?

Actually you could use either as these are differences in temperatures, rather than actual temperatures. If we convert all temperatures to Kelvin first then the differences between those temperatures will still be the same.
