Normaly there is no flow in a pitot tube, so the smooth schould be in the opening of the tube.
It's just a question of accurasy in the messure.
Is it really the total pressure you want ?
A typical pitot tube are used to result in the dynamik pressure whitch gives you speed / flow of the fluid...
You make me confused.
For me it is physics to calculate f.ex. the heat loss in a building, equippment as pipes, pump's, radiators and heatpump needed to keep the house warm.
Compare the calculations needed whith SI resp. Imperial units; is there no difference ?
I'm sorry if i expressed myself badly.
Offcourse you in this forum understand SI and it's benefits. That is why I am taking part in here.
What i meant was the uncovinience with the imperial units ( or what it's named) when dealing whith US technical matters, and US has some influence on the...
The area of a rektangel is for ex.
2 m • 4 m = 8 m^2
The area of a triangel is for ex.
2 m • 4 m /2 = 4 m^2
Make a diagram for velosity and time in the case of free fall and you get a triangel.
The area of this triangel is for the first second
1 s • 10/2 m/s = 5 m
( gravity 10 m/s^2, or 10...
I know SI is in use in U.S as well as other units are common everywhere
As a step on the way you can use both old units and SI (as for "cal" and "J" on all food declarations in sweden)
My point is that physics is hard enough to understand without unit conversions.
I had a student some years back...
Hello all friends of science
I am new in this nice forum and not so good in math, but i would appreciate a response on my view in this matter even if its late in this thread.
I think of the aspect "energy= pressure * volume"
If there is a different potential/energy (here inside the mouth versus...
I think you are clever.
Obviously there is an error in the conventions when energy equals torque.
Torque should have the unit Nm/rad.
That could be acceptable if radius defines as m/rad
Can anyone explain to me how it comes that US not have accepted the use of SI ?
Do you not understand the benefits ?
Would it not be more effective if the new generation of students could concentrate on understanding fundamental physics relations rather than struggle whith old-fashioned and...
As a kid i played with a spool and was fachinated abaut the fakt that the spool came closer too me even when it meant that the thred was winded up on the spool. There you have the force aspect in this matter.
Imagine you are in a train with no floor.
Put down a wheel, driven by the moving...
