Water flows through a 300mm 150mm horizontal venturimeter at the rate of 0.065mĀ³/s and the differential gauge is deflected 1.2m, as shown in the figure below. Specific gravity of manometric fluid is 1.6. The coefficient of discharge of the venturimeter will be (a) Cd=0.99 (b) Cd=0.98 (c) Cd=0.95 (d) Cd=0.92

Step 1
- The diameter of the inlet (D1) is 300 mm, so the radius (r1) is 150 mm or 0.15 m. The area (A1) is Ļr1Ā² = Ļ(0.15)Ā² = 0.0707 mĀ². - The diameter of the throat (D2) is 150 mm, so the radius (r2) is 75 mm or 0.075 m. The area (A2) is Ļr2Ā² = Ļ(0.075)Ā² = 0.0177 Show moreā¦

The fresh water behind a reservoir dam has depth $D=15 \mathrm{~m}$. A horizontal pipe $4.0 \mathrm{~cm}$ in diameter passes through the dam at depth $d=6.0 \mathrm{~m} .$ A plug secures the pipe opening. (a) Find the magnitude of the frictional force between plug and pipe wall. (b) The plug is removed. What water volume exits the pipe in $3.0 \mathrm{~h}$ ?
In Fig. $14-51,$ the fresh water behind a reservoir dam has depth $D=15 \mathrm{m} .$ A horizontal pipe 4.0 $\mathrm{cm}$ in diameter passes through the dam at depth $d=6.0 \mathrm{m} .$ A plug secures the pipe opening. (a) Find the magnitude of the frictional force between plug and pipe wall. (b) The plug is removed. What water volume exits the pipe in 3.0 $\mathrm{h} ?$
