Question

With what velocity does water flow
out of an orifice in a tank with gauge
pressure 4 x 105 N/m2 before the flow
starts? Density of water = 1000 kg/m².
[Ans. 28.28 m/s]​

Answer 1

 

Answer:

Here, P=3×105Nm−2,ρ=1000kgm−3,g=9.8ms−2

As P=hρg

∴h=Pρg=3×1051000×9.8m

Velocity of efflux,

v=2gh√=2×9.8×3×1051000×9.8√

=600√=24.495ms−1≈24.5ms−1
