2. Consider air flowing in a rectangular duct (e=.001", p=1.2 kg/m3, p=1.98x10-5 kg/m-s) with dimensions of 1 m by 2 m and a length of 100 m. There is a fan at the start of the duct that pulls in still air from the outside and accelerates it to some bulk velocity ub before discharging to the atmosphere. The air pressure right in front of the fan is 10 kPa gauge. Find the volumetric flow rate of air in the duct in m3/s. 2.
