    A house built on a riverside is to be cooled in summer by utilizing the cool water of the river, which flows at an average temperature of 15°C. A 17.8-m-long section of a circular duct of 20-cm diameter passes through the water. Air enters the underwater section of the duct at 39°C at a velocity of 3 m/s. Assuming the surface of the duct to be at the temperature of the water, determine the outlet temperature of air as it...
