Ahlem,

   The value that Type5 is looking for is sometimes referred to as the 
heat exchanger UA. You can look in a heat transfer text book or online 
for the methods used to compute it. Keep in mind that UA has units of 
kJ/h.K. The actual amount of heat transferred by the exchanger varies 
with inlet temperature but the heat transfer /coefficient /does not.

kind regards,

  David
