M342 Water flowing from the 075 in diameter outlet shown ris

M3.42 Water flowing from the 0.75 in. diameter outlet shown rises 2.8 inches above the outlet. Determine the flow rate.

Solution

Here Area = pi*D²/4

g = 32.2 ft/s²

Area = (3.14*0.75²)/4

= 0.441 in²

^{Velocity (V)= sqrt(2gh)}

^{= sqrt 2*32.2*2.8)}

^{= 13.42 ft/s}

^{Flow rate Q = A*V}

Q = 0.441*13.42

Q = 5.92 ft³/s
