How To Make A Pitot Tube

[@Bandicoot803]

Splendid at its best!!! That is truly some unsurpassed craftsmanship ever found on KZbin! Plus, no ads, no sponsor brag, no 8U77$#!+ music nagging in background, no unneccessary video effects, just pure video quality on a natural basis. Enjoyed it so much watching you assembling this Pitot Tube. I hope one day to make my own as I'm in possession of electronic pressure transducers. Might be a neat project to have fun with and to learn something from.

[@HotRodHolman]

Hi SNT, Thankyou so much for the kind words and comments. I guess my passion for WW2 Avionics comes through. I love your idea about electronic pressure transducers. Brilliant! A pitot tube is really quite a simple device, one forward facing tube, and one at 90 degrees. Put a transducer on each of these tubes, and your airspeed is simply proportional to the voltage difference. You could use a simple analog Volt meter to get this difference. Connect the static transducer output to the "-" meter input, and the dynamic transducer output to the "+" meter input. Of course you would have to calibrate the meter deflection in whatever velocity units you wanted (meters per second, etc.), but that would be fun. Thanks again for your comments. Let me know how you make out.

OK, that was awesome... Throw in some 400 volt heaters to prevent icing at altitude, and I think that would actually work on a jet airplane (It would be quite the kludge in a pinch, but he legit built a REAL PITOT tube...) I am impressed.

[@HotRodHolman]

Hi @Philstuf, Thank you so much for commenting on my Pitot Tube video. You made my day. It is very cool to me to know that others get as excited as I do about mechanics and physics, let alone historical WW2 stuff…

[@philstuf]

@@HotRodHolman Dude, that thing is awesome and as someone that considers myself to be a bit of a "renaissance man" in trying to know how most things work, this was absolutely fantastic. You LITERALLY built a REAL PITOT tube at home... That's some pioneer level stuff, man...

[@luiserodriguez7442]

I’m really impressed, I saw your video not just one but a bunch up times, I’m gonna build My own pitot tube thank to your video, thank you.

[@HotRodHolman]

Hi Luis, thanks for watching my video and commenting. It was really fun to make this pitot tube (and very inexpensive too), plus it was a real kick to see it actually work with my vintage air speed indicator. Let me know if you want to discuss this more. I can even send you drawings if you want. Remember, all the things you need to make this come right out of any good hardware store. Frank...

Sir can you please send me the names or images of components individually as soon as possible

[@JoeSevy]

Great! I've been wanting an accurate way to test blower fans. Exactly what I needed!

[@slimeroad]

Its a very good instructional video. Thanks for taking the trouble to prepare and share it.

[@mohamedfazil9643]

could i get a dimension of the pitot tube which you have made

[@HotRodHolman]

Hi Mohamed, Thank you for your interest in my pitot tube. Actually, the pitot tube is a fairly simple device for measuring airspeed, and the dimensions are not critical. It consists of 2 tubes, one facing into the direction of travel which captures total pressure (dynamic + static), and a second tube facing perpendicular to the direction of travel which measures just static pressure. (Note: Statis pressure is just the atmospheric pressure at what ever alltitude you are at. At sea level, it is 14.7 pounds per square inch). We want just the dynamic pressure, so we have: Dynamic Pressure = Total Pressure - Static Pressure Now, getting back to your question. My pitot tube was made entirely from copper tubing from Home Depot. I used 1/4 inch tubing for the inner tube (total pressure tube) and 1/2 inch tubing for the outer tube (static pressure tube). The total length is 10 inches. Finally, Airspeed is Proportional to Dynamic pressure. You will need some kind of system to measure this Dynamic pressure. I used a World War II Airspeed Indicator. You could also use modern day electronic pressure transducers. You could even use a column of water in a "U-shaped" graduated glass tube. It's not rocket science. Good Luck...

Sir. If you're still here in yt. Can you please teach me how to do that cause i need it for my thesis. Youre video is clear but i need some explanation. Thanks sir. I will wait for your response.

[@HotRodHolman]

Hi John, so nice to hear from you. Pitot tubes are actually quite a simple device. One tube facing forward, and a second tube facing at 90 degrees to the side. Then some kind of way to measure the difference in the pressure between the two tubes.

[@johnpauloyamat7533]

​@@HotRodHolman can you teach me how to do the different kinds of way? where can i contact you sir. thank you very much sir

[@HotRodHolman]

Hi John, yes I can teach you. Can we use email so I can include drawings if necessary. My email is [e-mail]

[@davidconnolly7693]

awesome video!! I've been wondering how you could make a pitot tube and this was so clear! thank you!

[@HotRodHolman]

Thanks David. It was very interesting to research this and find out how pitot tubes worked. Once I saw they were fairly simple devices, it was easy to come up with a design and make one.

[@chaerohrs7630]

This is awesome. I think it's very cool how you wanted to build it, so you just did.

[@RipRoaringGarage]

The irony of mounting a WW2 ASI on a Japanese car lol.

[@HotRodHolman]

Wow, great comment which totally escaped me. Thak you for your insight!

[@RipRoaringGarage]

@@HotRodHolman I still think its very cool. Cars make us do weird things. Merry Christmas!

[@tejasmohol6091]

Awesome job Mr. Frank. The way you did it was fantastic. Please keep posting

[@yasinbaseski5557]

Dear Mr. Frank., I am writing this to you from Turkey, where I am a student of Celal Bayar University. My major is Energy Systems Engineering and our fluid mechanics professor assigned us to do a project, therefore I decided to make a pitot tube and watched your video. I would like to say I found your video quite interesting! May I kindly ask for your valuable time to help me on ingredients of the tube and how to make it properly? Thank you very much for your attention. (I sent you an e-mail.)

[@AROD500500]

Great video, Going to purchase the parts and try assemble. Can you share where you purchased the used airspeed indicator. Thanks..!

[@irfanmajeed1]

great job. fantastic

[@mangekyoumusa]

How much did the pitot tube components cost in total?

[@riyadhkadom1442]

Daer can i get the parts dimensions and number to be able making obe please?

[@mohammedasim374]

Great video sir! I've been assigned a project to build pitot tube and it would be really helpful if you could tell me the names of the components I would need. Thanks in advance.

[@danialasyraf8284]

How can i find all that requirement stuff to make that pitot tubes

[@MarkSDCA]

Why don't you guys have a work bench?

[@70b_shuklabhupendra29]

Sir can you please send me the names or images of components individually as soon as possible

[@KilpMafia]

yo was this for an aeronautical engineering report?

[@ronaldfranck6960]

I'm not too crazy about you driving in on-coming traffic, holding the pitot tube apparatus out the window AND filming all at the same time. Jesus, just to find out if an old airspeed indicator works? What were you thinking? Next time 'ask a friend'.

[@HotRodHolman]

Hi Ronald, Thanks for watching my video and taking time to comment. Two things: 1) If you note, just before I walk outside to get in the test vehicle, I am filming myself in a mirror using a head mounted GoPro. My hands are completely free. 2) The Pitot tube is firmly mounted to the test vehicle roof. I am not holding anything. Result: Both hands are on the wheel, and both eyes are on the road at all times. I adjusted the head mount GoPro so that when I was watching the road, the GoPro was filming the Speed Indicator. I do take exception with your term "old airspeed indicator". It is a Vintage World War II Instrument, probably from an aircraft protecting the freedom of people like both you and me so that we could have this conversation 76 years later.

[@mangekyoumusa]

It doesn't take much to realize he did take precautions before driving. Did you skip most of the video or something?

[@ronaldfranck6960]

@@mangekyoumusa Ha Ha, it's a 15 minute video with one minute of it driving. How much of it do you think I missed? You say he took precautions? Like securing the airspeed indicator to the steering column with painter's masking tape? Precautions like driving 70 mph on a two lane rural roadway with oncoming traffic? Yea, he uses a head mounted video camera, ...so what? The camera sees only what he's looking at. It is still distracted driving. On top of that, it's a 400 mph airspeed indicator and he momentairly reaches 70 mph. Not an very useful evaluation of the pitot tube/airspeed indicator's accuracy. My point was that this little experiment wasn't worth he risk of a mishap happening. He's free to risk his own life and limb but that freedom doesn't extend to putting others at risk.

[@mangekyoumusa]

@@ronaldfranck6960 Your original comment implied he was juggling between driving, recording and holding the pitot tube at the same time like a maniac which blows what was going on out of proportion, which is what I was addressing. Nonetheless, you have a point in your response.
