Question:

Figure 9.20 shows a liquid-to-air heat exchanger in which air flows at 50 m3/h inside a rectangular passage and around a set of five vertical tubes. Each tube is a standard hydraulic steel tube, 15 mm OD × 1.2 mm wall. The air has a density of 1.15 kg/m3and a dynamic viscosity of 1.63 × 10-5Paˆ™s. Compute the Reynolds number for the air flow.

All dimensions in mm 96 18 50 Air flow between tubes
