Question

A velocity of flow of fluid of density $200\left(kg/m^3\right)$ is to be measured by the Pitot tube. If Pilot tube produces a differential pressure of $40kN/m^2$ then the velocity of flow $\left(inm/sec\right)$

• A. 20

Answer 1

The correct option is A 20
$\text{In case of Pitot tube, velocity is}$

$V=\sqrt{\frac{2\Delta P}{\rho }}$

$\rho =200\left(kg/m^3\right)$

$\Delta P=40\left(kN/m^2\right)$

$V=\sqrt{\frac{2\times 40\times {10}^3}{200}}=20\left(m/sec\right)$
