Question

The velocity of flow of water in a horizontal pipe is $10 m / sec$. Find the velocity of water at the top? $\left( g =9.8 m / s ^2\right)$

✓

Answer

If the velocity of liquid in the pipe is v ,
Velocity at top $=\frac{1}{2} \frac{ v ^2}{g}$
Here, $v =10 m / sec$ and $g =9.8 m / sec ^2$
Velocity of water at the top $=\frac{1}{2} \frac{(10)^2}{9.8}$
$
\begin{array}{l}
=\frac{100}{19.6}=\frac{1000}{196}=5.102 \\
\cong 5 m
\end{array}
