PITOT, PITOT-STATIC, VENTURI TUBE

Example

A Pitot-static tube is used to measure the velocity of helium in a pipe. The temperature and pressure are 5 degree celcius and 600kPaG. The pitot-static tube indicates a pressure difference of 100Pa. Determine the helium Velocity.

PV= nRuT

P=nRuT/V

P=pRuT/MrHe

(600+101)x10^3=p(8.314472)(273.15+5)/0.004

p=(701x10^3)/(578167)

p=1.212 kg/L

V=Sqrt(2(P2-P1)/p

V=Sqrt(2(100)/1.212)

V=12.8L/s

Try this yourself

Air is flowing in a duct. The pressure-difference gage attached to the pitot-static tube indicates a difference of 200 Pa. What is the air velocity? (ρair = 1.20 kg/m3 )
