Question details

Water is to be heated from 15 deg C to 65 deg C as it flows through a 3-cm-internal-diameter 5- m-long tube. The tube is equipped with an electrical resistance heater that provides uniform heating throughout the surface of the tube. If the system is to provide water at the rate of 10 L/min, determine the power rating of the resistance heater. Also estimate the inner surface temperature of the pipe at the exit.
