Water is heated by submerging 50 mm-diameter, thin-walled copper tubes in a tank and passing hot combustion gases (Ig = 750 K) through the tubes. To enhance heat transfer to the water, four straight fins of uniform cross section, which form a cross, are inserted in each tube. The fins are 5 mm thick and are also made of copper (k = 400 W/m.K). If the tube surface temperature is T= 350 K and the mass flow rate of gas = 1.1 kg/s. What is the overall efficiency of the fins? Treat gas as air.

Consider a large plane wall of thickness 2L=20mm. Both surfaces of the wall are convectively cooled by the surrounding coolant at To = 250°C with a heat transfer coefficient of h= 1100 W/m².K. A fuel element of a nuclear reactor is considered in the shape of this large plane wall with given constant thermal properties as thermal conductivity k = 30 W/m.K and a = 5 x 10-6m²/s. It is known that heat is generated uniformly within the element at a volumetric rate of q = 1x 107W /m³. A departure from the steady-state conditions associated with normal operation will occur if there is a change in the generation rate. Consider a sudden change to q2 = 2 x 107W/m³. Assuming steady one-dimensional heat transfer along the wall, use the explicit finite- difference method to show how to calculate temperature To at 1.2 sec and temperature Ts at 1.5 sec.

Oil whose temperature is 30°C is flowed through a pipe with a diameter of 50 cm. The pipe is in an environment where the temperature is 20°C. So that not a lot of heat comes out of the pipe, the pipe is wrapped with an insulating material (k = 0.007 W/mK) as thick as 5 cm. If the convection coefficient of the outer surface of the pipe is 12 W/m²K, calculate the heat flow from the pipe per meter of length.

This problem is for us to practice convection coefficient calculation for internal flow. You will have to design a water heating system that will heat up water flowing at 1 kg/s from 10°C to 40°C. You have to chose from two heated ducts - (a) one with rectangular cross-section of 0.6 mx1.2 m and (b) the other with 15 cm diameter circular pipe. Both ducts are maintained at a constant temperature of 60°C. Assuming that the flow is fully devloped in both cases, compare the length required for the two ducts to reach the deasired water temperature. Comment on whether the fully-developed assumption is justifiable in both cases.
