Fuel oil is to be cooled in a double-pipe heat exchanger of length 2 m made of stainless steel that has a conductivity of 15 W/m K. The inner tube has inner diameter 1.2 cm and outer diameter 1.8 cm. The convection heat transfer coefficient on the inner surface of the tube is 850 W/m2 K and 1250 W/m2 K on the outer surface. Consider a fouling factor of 0.0004 m2 K/W on the inner surface and 0.0001 m? K/W on the outer surface. Estimate the () Total thermal resistance. (ii) Overall heat transfer coefficient based on the inner area (iii) Overall heat transfer coefficient based on the outer area.
