Water is entering a heated tube at mass ow rate of 1.2 kg/s. The temperature at the inlet is

20 C and at the outlet is 80 C. Assume the surface temperature of the tube is 100 C. The convection

coe cient of the water ow is 28 W=m2  C. The speci c heat and density of water can be assumed to

be 4180 J=kg  C and 990 kg=m3. What is the rate of heat transfer to water during this proces
