Mercury at an inlet temperature of 75 °C flows through a 2 cm inside diameter tube at a flow rate of 1.5 kg/s. This tube is part of a nuclear reactor in which heat can be generated uniformly at any desired rate by adjusting the neutron flux level. Determine convection heat transfer coefficient, and the heat flux required for a 1.5 m length of tube required to raise the temperature of the mercury to 275 °C. Also determine if mercury vapor is generated with calculating the outlet wall temperature. The boiling point of mercury is 355 °C.

Water (inlet temperature of 30 C) flows at rate of 3.4 kg/s through a 30 cm diameter aluminium tube. You intend to heat the water to 40 C at the exit of this tube. It is recorded that the surface temperature of the tube is 98 C. Evaluate the length of tube required for this condition. Assume fully developed flow. Then, compare your calculated length with 4 m, comment on the water exit temperature if the tube length is changed...

Kerosene enters a 5 cm diameter tube at 35C with a velocity of 3 m/s. The tube is wrapped with a resistance heating element so that when it is energized a uniform heat flux is imposed on the tube. At the exit of the tube, the temperature of the kerosene is to be 45C. A constraint is placed on the process, such that the local kerosene temperature cannot exceed 80C; this is likely to occur at the wall of the...
