Air at 105 kPa and 25°C flows from a 7.5-cm circular duct into a 22.5-cm circular duct. The downstream pressure is 6.5 mm of water higher than the upstream pressure. a. Determine the average air velocity approaching the expansion (in m/s). b. Determine the volumetric flow rate (in m3/s). c. Determine the mass flow rate (in kg/s).
