A 2.5 cm inside diameter pipe is being used to convey a liquid food at 80ºC. The inside convective heat transfer coefficient is 10W/(m2ºC). The pipe (0.5 cm thick) is made of steel (thermal conductivity = 43W/mºC). The outside ambient temperature is 20ºC. The outside convective heat-transfer coefficient is 100 /(m2ºC). Calculate the overall heat transfer coefficient and the heat loss from 1 m length of the pipe.

A can of soft drink, 12-cm high and 6-cm diameter, is initially at 20°C. It is placed in a refrigerator where the air is at 0°C. The convective heat transfer coefficient associated with the outer surface of the can is 10 W/m2 °C. Assuming the properties of the drink to be those of water and that the heat capacity of the container is negligible, estimate the time taken for the temperature of the drink to reach 5°C.

The condenser of a large steam power plant is a heat exchanger in which steam is condensed to liquid water. Assume the condenser to be a parallel flow shell-and-tube heat exchanger consisting of a single shell and 10,000 tubes, each executing two passes. The tubes are of thin wall construction with D = 30 mm and the steam condenses on their outer surface. The heat transfer rate that must be effected by the exchanger is Q = 2 × 10^9...
