Water enters a smooth-thin-walled tube of 1 inch in internal diameter at 50F and leaves at 150F. Heat is supplied to the water by condensing steam on the surface of the tube at a constant temperture of 250F. For a water flow rate of 1.5 Ibm/s (assuming fully developed flow determine:
heat transfer coeffficent for water inside tube, length of the tube required for this heating, the water pressure drop and pumping power required to overcome the presssure drop.
