WebSTEP 3 : Calculate the air side heat transfer coefficient The following formula is applied to calculate the air side heat transfer coefficient, depending on the density of fins on the tubes : With : h a = heat exchange coefficient on air side (BTU/h.ft 2 .F) FV = face velocity (see table 1) (ft/min) 4. WebHeat-transfer in heat exchangers are reduced by fouling. During operation with liquids and gases a dirt film may build up on the heat exchanger surfaces . The deposit film is referred to as fouling . Increased thermal resistance caused by the deposit can normally only be obtained from tests or experience. The fouling factor can be determined as.
