A 1.5cm inside diameter tube has water flowing in it at a flow rate such that the Reynolds number is 50,000. The water enters the tube at 10oC and the tube wall temperature is maintained at 15oC higher than the average water bulk temperature. Calculate:

a) the amount of heat transfer required to achieve a 10oC increase in water temperature (in W)

b) the length of the tube to achieve this amount of heat transfer (in meters)
