Engine oil flows at a rate of 1 kg/s through a 5-mmdiameter straight tube. The oil has an inlet temperature of 45 C and it is desired to heat the oil to a mean temperature of 80 C at the exit of the tube. The surface of the tube is maintained at 150 C. Determine the required length of the tube. Hint: Calculate the Reynolds numbers at the entrance and exit of the tube before proceeding with your analysi
