Using the same information, determine what would be the change of heat transfer rate between clean and fouled operations. Assume the heat transfer area and the mean temperature difference of the fluid streams to be invariant.of29. A water-water gasketed plate heat exchanger has an overall heat transfer coefficient under fouled conditions of 4200 W/m² . K. Hot- and cold-fluid-side heat transfer coefficients are 15,000 and 14,000 W/m² . K, respectively. The plate thickness (stainless steel 316) is 0.6mm, and the thermal conductivity is 17 W/m . K. Calculate the cleanliness factor CF and the total fouling resistance for this exchanger.
