Problem #4 (30 Points) Air at 110 kPa and 323°K flows upward through a 0.06m diameter inclined duct at a volume flow rate of 0.045 m3/s. The duct diameter is then reduced to 0.04m through a reducer. The pressure change across the reducer is measured by a water monometer (Density 1000 kg/m3) The elevation difference between the two points on the center of the pipe where the two arms of the monometer are attached is 0.2m. (1) Determine the density...
A fan draws air from the atmosphere through a 0.3 m diameter round duct that has a smoothly rounded entrance. A differential manometer connected to an opening in the wall of the duct shows a vacuum pressure of 2.5 cm of water. The density of air is 1.22 kg/m3. (a) Determine the volume rate of air flow in the duct in cubic feet per second. (b) What is the power of the fan? Fan 0.30 m 2.5 cm Fan 0.30...
Water flows steadily downwards through a circular pipe of internal diameter 0.15 m inclined at 30° to the horizontal. A U-tube manometer is used to determine the pressure difference between two points displaced axially along the pipe by a distance 1.25 m. The reading on the manometer is 0.25 m of mercury. 1.25 m 0.15 m 30 0.25 m mercury Figure 2: Manometer and pipe Neglecting the thickness of the wall, determine between points 1 and 2: a. The difference...
