If the fluid (density of 1040 kg/m*3) leaves a fire extinguisher at a speed of 25 m/s, what is the pressure inside? Submit Answer | Incompatible units.

Explanation / Answer

Here ,

density of fluid , p = 1040 Kg/m^3

speed of fire extingusher , v = 25 m/s

let the pressure inside is Pi

Using Bernoulli's equation

0.5 * (Pi - Po) = 0.5 * p * v^2

0.5 * (Pi - 1.01 *10^5) = 0.5 * 1040 * 25^2

solving for Pi

Pi =4.26 *10^5 Pa

the pressure inside is 4.26 *10^5 Pa
