question

Water is moving through a heat exchanger tube with an inside diameter of D = 1.25 in. and a length of L = 9.0 ft. The water enters at 45°F, with a flow rate of 18 gal/min. The wall temperature is constant at 200°F. Determine the exit temperature of the water using analogies of Reynolds, Colburn,Prandtland von Karman.
