3. ( 20 points) Air \( (\mathrm{MW}=28.97) \) at 16.39 psia and \( 113^{\circ} \mathrm{F} \) flows upward through a 2.68 in diameter inclined duct at a rate of \( 2.3 \mathrm{ft}^{3} / \mathrm{s} \). The duct diameter is then reduced to 1.89 inches through a reducer. The pressure change across the reducer is measured by a water manometer. Determine the differential height between the fluid levels of the two arms of the manometer in inches. You may assume the kinetic energy correction factors are 1.05.

Step 1
- Temperature: \(113^\circ \text{F} = 113 + 459.67 = 572.67 \, \text{R}\) - Pressure: \(16.39 \, \text{psia} = 16.39 \times 144 \, \text{lb/ft}^2 = 2358.16 \, \text{lb/ft}^2\) Show more…
