To cool the hot oil, an engineer has suggested that the oil be pumped through a submerged pipe in a nearby lake. The pipe (external diameter = 20 cm) will be placed in the horizontal direction. The average pipe outer surface temperature is 130 °C. The temperature of the surrounding water is assumed to be constant at 10 °C. Pipe length 150 m. If it is assumed that there is no movement of water. a. Determine the convective heat transfer coefficient of the outer pipe surface to the water. =Answer Watts/ (m² °C) b. Determine the rate of heat transfer from the pipe to the water. =Answer kW
