For a shell-and-tube heat exchanger, the clean overall heat transfer coefficient is calculated as 250 W m-2K-1 for a specific process condition. It is expected that the heat exchanger may be fouled during the operation, and a fouling resistance of 0.001 m2K W-1 is prescribed. The dirt overall heat transfer coefficient is W m-2K-1.
