Dang. I've listened to a ton of people and watched as many youtube videos. You sir, have hit the nail on the head. I am now confident and ready to work. Thank you.

@alexandraquintal26 2 года назад

Amazing video! Finally understood how to correctly use a pitot tube and feel confident enough to conduct my testing! Thank you so much, everything well explained, it all makes sense now!

@Stefan_Kawalec 2 года назад

Sir, you have an amazing pedagogical gift. Great tutorial.

@sanjuro720 4 года назад

Thank you for the tutorial. I'm a NEBOSH Diploma student and have exam questions on LEV systems and transport velocity. Really helpful.

useful video I understand the Pitot tube, but we are looking for briefing note for more information as you mentioned in your video.

superb....amazing work..you are doing very helpful work for Engineering students......Thank you.........Keep it up.......

@oxyl8ltd41 7 лет назад

Thank you Pritesh. Next video series will be on the design, assessment and measurements to be taken at Captor Hoods (such as welding hoods). Ideas for teaching videos always welcome.

@pankajyadav-tatasteelstrip6837 7 месяцев назад

nice explanation. Thanks. Further I have few query n my mind. What will be the effect on static pressure and total pressure if their is damaged in duct line and addition air infiltrating into the duct apart from the design please.

@christopherdahle9985 3 года назад

Thanks, gave me the basics so I can build my own pitot tube to measure the airflow in my dust collection system. Now I just need to figure how to make and calibrate a manometer.

@aykutgurkan7008 3 года назад

I do not recommend using a pitot in dust collecting units. Small holes in the pitot tube can become blocked.

@christopherdahle9985 3 года назад

@@aykutgurkan7008 Thanks for the tip. If you have a suggestion of a better way to make and use cheap/free home made sensors and instruments to gauge the performance of a dust collection system in a hobby work shop, I'm most definitely interested. Actually though, the big worry is that a big chunk of something will get sucked through one of the blast gates, rattle down the duct and smash the pitot tube, or get hung up on the pitot, clogging the duct, which is why I rejected...blah blah 3d printed impeller...encoder from an old mouse...blah blah Arduino...display....wires...code..of some sort inside the duct. All I really care about is relative performance so a water column and some marks on the wall showing how much vacuum I can pull when the filter is clean and the system is working is maybe a slightly better system than "Huh, the dust hood for the miter saw isn't working all that well today....maybe I ought to dump the dust bin"

@brunomarswalangganon4229 6 лет назад

Please help me understand log-Tchebycheff method. How are the traverse points placed? Are there any mathematical formulas used to know their locations in the cross-sectional area? Thanks. I'll really appreciate a feedback as soon as possible.

@VideoShingas Год назад

How should I interpret the Negative Static pressure you measure? To get Total Pressure do I add the negative static pressure value to the Velocity Pressure? Or do in use the absolute value of the measured (and negative) static press (ie treat it as a positive value)?

@ahmadsaleem5332 5 лет назад

Thank you a lot for this amazing helpful video, but I have a question,How I can measure the airflow for a compressed air system using this device to check the compressor efficiency ?

@oxyl8ltd41 5 лет назад

Hi Ahmad. Difficulty would be getting the instrument into the pipe and yet maintaining a seal. Not sure it can work in your application? Regards, Bill

@eduAutomacao 7 лет назад

amazing !!! I'm building a wind tunnel and I'm looking for a pitot tube to,measure the air speed...

@bobbauvian7700 Месяц назад

can this unit be used to measure cfm air movement in a vacuum or compressed air tube of 1/2 inch ID diameter?

@Sechelanji 6 лет назад

Can you use this instrument to measure duct leakage?

@oxyl8ltd41 6 лет назад

It can be used only to measure air flows in a ducted system. Duct leakage is usually measured from pressure loss using a manometer. You might find this document useful:- tc0502.ashraetcs.org/documents/presentations/Need_for_Duct_Leakage.pdf

@poker5147 Год назад

How do I measure this on a large air handling unit fan with a large duct? Where my pitot tube can't even reach the middle of the duct because the cross sectional area is so large?

@oxyl8ltd41 Год назад

Ah! Then you need a big Pitot. You can purchase Pitots up to 3m long to my knowledge.

@anonlakh3388 3 года назад

Why readings are minus ..?

@monotoshroychowdhury7202 Год назад

Sir we know V = ✓2gh where h equals to velocity pressure and volume equals to area of duct x velocity . Now how do you find V= 1.29✓velocity pressure . Somewhere I find V= 1096.7✓velocity pressure ÷ density where density is 1.23 lb/ cu ft air at barometric pressure 29.45 hg column and atmosphere temp is 460 + 75 °f . . Pl text how do u find 1.29 ?

@kkww5034 2 года назад

Can you please share the pdf

@monotoshroychowdhury7202 Год назад

Sir what is 1.29 and how this no you find ? Pl share .

@oxyl8ltd41 Год назад

Sorry - I do not monitor this question log - but here is your (very) late answer. The full formula is (for metric conversions only) - V (velocity) = SQRT(Vp/0.5p) where p = air density. But in most cases we use Pitots in duct at around 20C where the air density is 1.2Kg/m3. If we put that figure into the main equation we could reduce it/simplify it to V=1.29SQRT(Vp) ...... but ONLY if the air in the duct is around 20C - otherwise you need to use the full equation.
