What is the product of overall heat transfer coefficient and area (UA) for a heat transfer equipment with the geometry as shown in the diagram? The inner tube (the shaded area in the figure) is made of a material with thermal conductivity of 1.2 W/m.K. The convection coefficient of the hot fluid (in the inner tube) is 25 W/m².K and that of the cold fluid is 12 W/m².K. The dimensions shown in the figure are r₁ 0.1 m, r₂ = 0.15 m, and r3 = 0.3 m.

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.
