A bent tube is lowered into water stream as shown in the Fig. The velocity of the stream relative to the tube is equal to $v = 2 m / s$ . The closed upper end of the tube located at height $h_{0} = 10 c m$ above free surface of water has a small orifice. To what height h will the water get spurt?

40 cm

20 cm

10 cm

5 cm

Right Answer is: C

SOLUTION

Applying Bernoulli's theorem for points 1 and 2 of the streamline shown

$P_{0} \to$ Atmospheric pressure

$\frac{1}{2} ρ V^{2} + (P_{0} + ρ g h^{'}) + 0 = 0 + P_{0} + ρ g (h^{'} + h_{0} + h)$

$\Rightarrow h = 10 c m$
