[@emilymaze6616]

fluid mechanics by itachi. my dream has come true. i had quick question, if say we have 6 pitot tubes in a large tube, can we use the velocity distribution on the pitot tubes, to calculate volumetric flow rate of the large tube? if so, how does one do this or how does one find a relationship between velocity going in the pitot tube to the pitot position distance. thanks once again itachi

[@NiLTime]

If the Flow is in-compressible, steady, streamline (idle) then of course you can use Pitot tube to calculate velocity, using the derived equation. To get velocity, Just identify the pressure (use pressure gauge) at different point and use in the equn of pitot tube (to get velocity). Then you can use use Poiseuille's law to predict the volume flow rate of water through this large pipe. But in real life that's impossible, Turbulence is almost always a factor in larger pipes, as is friction caused by the interaction of the fluid with the pipe walls. So to calculate Volume flow rate and and average velocity, you need other parameter like Pipe Diameter, length, friction factor,pipe roughness etc.. Pipe are always designed, in accordance with the flow rate and pressure that it can handle.

[@emilymaze6616]

@@NiLTime Thank you very much for your detailed answer. i have a follow up question. In the beginning of the video, you had connected 2 piezometer tubes. I am unsure on how the pressure in both the tubes are the same. Is it because of constant fluid velocity along the larger pipe? What if the velocity is different, would this differ the static pressures obtains in the two peizometer tubes? Also is there a video on your channel explaining the fundamentals of the peizometer tube? Thank you once again and i appreciate you taking the time to make such amazing videos^.^ PS- this is an edit. i found the piezometer head loss video on your channel. That explained my question above^. Thx. i am still a bit confused as to how would one find the total pressure at a peizometer tube, given the initial velocity at the inlet of the large pipe and the distance from the inlet the the pipe. Is there an equation that could do this or do we have to manually put a pitot tube directly below the peizometer in order to measure velocity and thus find the total pressure at that tap? I am considering a large pipe where there are 10 static taps with different heads and the flow is not steady that is two streams of unequal velocity are mixing together and since there is a pressure drop, will we have to keep a peizometer at each static tap in order to measure the velocity at that point or can we find velocity from the distance and initial velocities of the two streams.

[@NiLTime]

@@emilymaze6616 In this video, Static pressure in both piezometer are same because the fluid is ideal and also have constant velocity. Increasing Velocity decreases static pressure and vice versa. If you consider friction then of course static pressure and dynamic pressure would decrease along the length of pipe. For the next part, with piezometer you can only get static pressure, not total pressure. For total pressure use pitot tube. You can calculate local velocity at different point using combination of piezometer and a pitot tube. Pitot gives total pressure. Piezometer gives static pressure. subtract them to get velocity. You can also use "Pitot-Static" tube. It is more precise and donot require piezometer. Hope that helps and enjoy reading ^^ .

[@thanhmai8582]

I have a question, in case tube measuring static pressure, the fluid level increase by its motion, using kinetic energy and come to stop, so why it not measure as total pressure?

[@PRABHATKUMAR-cc5ej]

Mam if static pressure are same at both point then how water flow from 1to2 because i study water flow from high pressure to low pressure it my dout please solve

If the fluid stops, does it mean tube 2 will become similar as tube 1 ? Thank you

[@NiLTime]

No. Tube 2 (pitot) will experience greater pressure than tube one. This greater pressure is dynamic pressure. Static pressure is similar on both tube.

[@emmadenisi1606]

@@NiLTime thank you but i dont quite understand… i understand what happen when the fluid is dynamic but i was trying to imagine what would happen if the fluid were static (i was asked that question in an exercice..) my thought were that if the dynamic pressure is experiencing in tube 2, in static condition tube 2 will experience drop pressure and the fluid level in the tube will drop too, but will it be the same level as tube 1 or there will be a différent level in both tube ? (I’m really sorry for my english, i hope what i’m saying is still understandable..)
