In a food processing plant, a steel pipe (thermal conductivity 17 W/m °C, internal diameter 5 cm; thickness 3 mm) is being used to transport a liquid food. The inside surface temperature of the pipe is at 95°C. A 4-cm thick insulation (thermal conductivity 0.03 W/m °C) is wrapped around the pipe. The outside surface temperature of the insulation is 30°C. Calculate the rate of heat transfer per unit length of the pipe.
