Question

A Pitot tube is used to measure the mean velocity of high pressure gas in a $0.15 m$ diameter pipe. At maximum flow rate the Pitot differential pressure is $250 P a$ . If the density of gas is $5 k g / m^{3}$ , then the mean velocity of the gas at maximum flow rate is ____ $m / s e c$ .
10

Solution

The correct option is A 10
$For Pilot tube,$

$mean velocity (v) = \sqrt{\frac{2}{ρ} Δ P}$

$= \sqrt{\frac{2}{5} \times 250} = 10 m / s e c$
