Consider a 50-mm-diameter and 25-m-long smooth tube that is maintained at a constant surface temperature. Fluids enter the tube at 30oC with a mass flow rate of 0.02 kg/s. Determine the tube surface temperatures necessary to heat water, engine oil, and liquid mercury to the desired outlet tem-perature of 170o
