Question

2. (10 points) A uniform air flow in a duct of 10 cm diameter is connected a manometer using working fluid of specific gravity of 0.7. The square well of the slant-tube manometer is sufficiently large that the elevation of the manometer fluid in it does not change T-200 significantly when fluid moves up in the leg of the manometer. When there is no flow in the duct, the liquid surface in the manometer les at 2.3 cm measured on the slanted scale. When an air flows in the duct with a density of 1.8 kg/m3, the liquid moves ' up to 6.7 cm. Find the discharge of the air in the duck-c 10 cm 30 s 0.7
