question

Steam condenses on the outer surface of a pipe. The coefficient of heat transfer is known to be 10,500 W/m^2-°K and the temperature is 107.8°C. Meanwhile, the interior is cooled by a flow of water, measured at a velocity of 2.44 m/sec and a mean bulk temperature of 65.6°C. It is a 2.54 cm schedule 40 steel pipe, with a length of 0.305 m. Find (a) the coefficient of heat transfer from forced convection of the water, (b) the overall heat transfer coefficient based on the inside surface area, and (c) the rate of heat transfer to the water.
