Question:
Oil enters a circular tube (3mm diameter) at 0 degree C that is surrounded by a heating fluid at 100 degree C. Assume the Nu outside the tube is 1 and the thermal conductivity of the heating fluid is 0.5W/m-K. The Nu number inside the tube is unknown. The velocity of the oil is 0.1m/s. Properties of the oil are in the picture.
Assuming a constant wall temperature, estimate the length of the tube needed for the bulk (or mean) temperature of the oil to reach 95 degree C.
