A 10-mm diameter tube has a maintained surface temperature of 200°C. Engine oil enters the tube at 70°C at a flow rate of 0.5 kg/s and exits at 105°C. Find the length, in m, of the tube and well as the corresponding heat transfer rate, in W. Assume fully developed flow and use the Dittus–Boelter equation to calculate the average Nusselt number.
