To cool the hot oil, an engineer has suggested that the oil be pumped through a pipe submerged in a nearby lake. The pipe (external diameter = 20 cm) will be placed in the horizontal direction. The temperature of the outer surface of the pipe averages 130 ° C. The surrounding water temperature is assumed to be constant at 10 ° C. Pipe length 100 m. If it is assumed that there is no water movement. a. Determine the convective heat transfer coefficient of the outer pipe surface to the water. = Answer Watt / (m² ° C) b. Determine the heat transfer rate from the pipe to the water. = Answer kW
