I always wondered how a Pitot tube works even after taking a fluid mechanics class. Now I know how it works. Thanks to this wonderful video.

Decent explanation for my fluid mechanics exam. It could do with some of the equations used e.g. bernoulli's eqn. maybe in the comments.

it is an averaging pitot tube, formally known as annubar

I think this is an annubar. Pitot tubes do not have multiple holes. That's the only diffrence between pitot tube and annubar.

Hello Endress+Hauser. In the current video it's mentioned flow measurements on chimneys, in this case, how to guarantee that the pressure differential read by the Endress+Hauser device is big enough to beat range of uncertainties of the measurement since Static Pressure in Chimneys are considerably low (like atm low)? I appreciate in advance, thanks!

Just curious and I am not trying to reinvent the wheel but can vacuum offer the same result?. What I mean is to have air speed over an opening facing opposite the direction of the craft's travel that creates a vacuum. It would seem to me a faster speed would create a higher vacuum. If actually feasible this could eliminate the deficiencies of a pressurized unit to have as a back-up.
@endresshauser6 жыл бұрын
Basically this is correct. Unfortunately, this will not work as for the measurement we need the difference in pressure before and after the obstacle. If going over a reverse facing opening, you're creating a vacuum which may be not repeatable with different line pressures. But thanks anyway for the idea.

I think the front of the probe measures stagnation pressure not dynamic pressure.

Is it for measuring flow or velocity ?
@josealbertogonzalezsaucedo98566 жыл бұрын
It measures velocity, but with a simple ecuation you can calculate the flow of the fluid in the pipe Q=v*A where A is the cross sectional area of the pipe and Q is the volume flow.

how pitot tube able to move the diaphragm ?
@endresshauser7 жыл бұрын
The pressure from the pipe containing gas, steam or liquid is transported via the pitot tube to the membrane of the differential pressure transmitter. Here the membrane is deflected depending on the differential pressure created by the flowrate of the media.
@polymath2877 жыл бұрын
Wouldn't it be better if instead of mounting the pitot tube from the top, we mount it by the side so the measured hydrostatic pressure is the same for all openings on the pitot tube? That's not the case if the pitot tube is mounted from the top since the openings that are deeper into the fluid read greater hydrostatic pressure.
@endresshauser7 жыл бұрын
Due to the fact that the average Pitot tube principle is based on the measurement of the dynamic pressure on different levels into the pipe and not on the static nor the hydrostatic pressure. Because these both pressures are compensated / eliminated by the openings at the back of the Pitot tube. To establish the dp-flow equation from the Bernoulli equation, the hydrostatic pressure is not taken in consideration. So I do not think that the hydrostatic pressure has an influence in the measurement, at least not in the real world. Maybe in a pure theoretical world.

It's true, they're based on the same principal... Now I know that the Prandt tubes is a type of Pitot tube known as Pito-static tube.

I guess they can't call it annubar because Rosemount registered the name.
