Q. An L-shaped tube with a small orifice is held in a water stream as shown in the figure. The upper end of the tube is $10.6\, cm$ above the surface of water. What will be the height of the jet of water coming from the orifice?

Velocity of water stream is $2.45\, m / s$.

Mechanical Properties of Fluids

Solution:

According to Bernoulli's theorem, $h=\frac{v^{2}}{2 g}$
$\Rightarrow h=\frac{(2.45)^{2}}{2 \times 10}=0.314=31.4\, cm$
$\therefore$ Height of jet coming from orifice $=31.4-10.6$
$=20.8\, cm$
