A 2.5 cm inside diameter pipe is being used to convey a liquid food at 80C. The inside

convective heat transfer coefficient is 10W/m2C. The pipe (0.5 cm thick) is made of steel

(thermal conductivity 43W/mC). The outside ambient temperature is 20C. The outside

convective heat-transfer coefficient is 100 W/(m2C). Calculate the overall heat transfer

coefficient and the heat loss from 1 m length of the pipe.
