An axial fan operating at 1000 rp. has the characteristics shown in Fig. $\mathrm{P} 12.42 .$ It delivers $15^{\circ} \mathrm{C}$ atmospheric air throagh a $50-\mathrm{cm}$ I.D., galvanized, sheet-metal, horizontal duct having a length of $175 \mathrm{m}$ and seven $90^{\circ}$ long-radius elbows. For constant air density what is the flow rate if the duct discharges to the atmosphere $^{\text {th }}$
A cylindrical air duct in an air conditioning system has a length of 3.5 m and a radius of 5.00 10-2 m. A fan forces air (? = 1.8 multiplied by 10-5 Pa·s) through the duct, such that the air in a room (volume = 242 m3) is replenished every 12 minutes. Determine the difference in pressure between the ends of the air duct.
