Question:
A cross-flow heat exchanger consists of a bundle of 32 tubes in a 0.6-m2 duct. Hot water at 150°C and a mean velocity of 0.5 m/s enters the tubes having inner and outer diameters of 10.2 and 12.5 mm. Atmospheric air at 10°C enters the exchanger with a volumetric flow rate of 1.0 m3/s. The convection heat transfer coefficient on the tube outer surfaces is 400 W/m2 ∙ K. Estimate the fluid outlet temperatures.
