Water flows at a rate of 10 cm3/s through a tube of 15 mm ID. The tube wall is maintained at a constant temperature of 60 °C. Calculate the local heat transfer coefficient at a distance of 1.0 m from the entrance of the tube. Also calculate the average value of the heat transfer co-efficient between x= 0 and x= 1.0 m. If the water enters the tube at a uniform temperature of 20 °C, determine the amount of heat transferred from the tube wall to the water over the first 1-m length of the tube.
