BTU 5. A heat exchanger has been designed based on calculated Uc (clean H.T coefficient) equal to 50; h. ft².°F h. ft².°F and BTU a dirt/fouling factor of 0.005 Do you think that the exchanger will have an "apparent overdesign" (i.e., the initial area will be different from the final area once the HX is fouled) for some period after installation? What is the apparent % excess area at the start, assuming no change in q?

Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
