A compact heat exchanger uses finned tubes as shown in Figure 9-30, spacing B. Determine the pressure drop and the convective heat transfer coefficient for air passing around the finned tubes at 27ºC, 5 m/s and with viscosity of 0.02 g/m?s. Air leaves the finned tubes at 100ºC. Also, determine the heat exchanger volume per unit surface area of heat exchange.
