Question

2) A Pitot Tube is used to measure velocity (the working fluid is air at sea level under standard pressure condition) and it is connected to a U manometer. If the fluid in the manometer is an alcohol with density p=800 Kg/m and the fluid velocity is 20m/s, calculate the displacement of the alcohol in the manometer.

Answer 1

In the problem they have mentioned that the working fluid is air all the properties will be taken at sea level under standard pressure condition. Density of air rhi = 1.225 kg/m^3.

The pitot tube is connected to the U tube manometer and the fluid in the manometer is alcohol ( density = 800 kg /m^3)

Also the fluid velocity is given V = 20 m/s
