The answer varies, depending on the type of heat exchanger. For a shell and tube, hairpin, or a plate heat exchanger, we will need the following information:
Five of the following:
– Warm fluid inlet temperature
– Warm fluid outlet temperature
– Warm fluid flow rate
– Cold fluid inlet temperature
– Cold fluid outlet temperature
– Cold fluid flow rate
– Each side of the exchanger needs at least two values from the above list. – Or, heat load and four values from above list (Again, need two values from each side.)
