Heat is transferred from one fluid to a second fluid across a metal wall. The film coefficients are 1.2 and 1.7 kW/m². K. The metal is 6-mm thick and has a thermal conductivity of 19 W/m.K. On one side of the wall there is a scale deposit with a fouling factor estimated at 830 W/m2.K. Calculate the overall heat- transfer coefficient.
