Engine oil enters a straight tube with a flow rate of 1 kg/s. The tube has a diameter of 5 mm and the surface temperature of the tube is maintained at 150˚C. The engine oil has an inlet temperature 52˚C and it is desired to heat the oil to a mean temperature of 80˚C at the exit of the straight tube. The properties of the engine oil are k = 0.139 W/m.K, Pr = 834, cp = 2072 J/kg.K and μ = 5.62 x 10-2 N.s/m2 Assume the flow is at fully developed region, determine: (a) The required length of the tube. (b) The rate of heat transfers from the tube to the engine oil.
