Problem 2: Water flows in a horizontal pipe with an I.D. of 10cm (circular cross-section) and a length of 40 meters at a velocity of 1.25 m/sec. The water enters the pipe at a temperature of 20 C and is heated by the pipe wall so that it exits at 80 C. The system can be considered steady. Calculate the following: a) The mass flow rate of the water. b) The overall rate of heat addition to the flow (in W or kw). c) The (average) rate of heat transfer to the flow per square cm of pipe wall area (W/cm2).
