For a shell-and-tube heat exchanger, the clean overall heat transfer coefficient is calculated as 250 W m–2 K–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 m2 K W–1 is prescribed. The dirt overall heat transfer coefficient is_______W m–2 K–1.
