YES...I can because I am a mechanical engineer with two degrees in Mechanical Science.
Bull s*** rubbish on YouTube
Of course there is force applied to the tube. Reason being is that a rocket is not closed at one end and has nothing to do with a vacuum cleaner.
The venturous funnelling at the end of the rocket allows gas compression to apply Force 'F' at exponential as mass 'M' decreases during fuel evacuation.
Oxygen is supplied to the rocket fuel as atmospheric oxygen decreases as to allow more heat energy to increase velocity.
Anyone can see that a simple firework rocket can do the same thing. (go out and buy one)
However it can be said that a thrust vortex is created through the rapid expelation of gasses within the tube of a firework rocket because the burning is prolonged by the rotational flow of gunpowder within the sides of the tube.
Going back to the video, it has sod all to do with force on the pipe.
The pipe is connected to the rocket as both gravitation with mass exert opposing forces as in Newtons 3rd Law of Motion.
The resistance being gravitation at 8.11g per m^2 which as the rocket escapes gravitation pull...'G' is decreased allowing 'a' to increase.once in space force 'F' allows the rocket to travel with a small resistance as there is no opposing force 'F' to overcome. Friction decreases as air becomes thinner allowing cooling.
So what the heck is the author on about a small hole in the side????
Common sense tells us that gas would escape and then there would be no force. Why a hole in the side????
Take a straw and try and suck liquid through it with a hole in the side. No liquid will flow which is more or less what the author is saying....but why the extra hole???
The whole emphasis here is that the thrust is pushing on the mass of the rocket. being greater than. gravitation.
Pressure gradient force if you like. The example is rubbish the air at the back of your head is is NOT PUSHING YOU hence the difference
You are in fact apply RESISTANCE
by both your own mass hence you feel no air in front of you. If the wind was to propel you forward at an alarming speed, the force of air in front of you would be greater than the air behind. Again...a load of rubbish in the video.
Any idiot could see that if you rode a bicycle the air flow on your face would be greater than the air flow at the back of your head because you are also moving away from the back flow of air by peddling forward. If you were stationary on your bike and the air behind pushed you, it would decrease and you would feel the air resistance on your face BECAUSE YOU ARE MOVING! That word 'MOVING' Not a tube with the hole in it's side
Ia m not impressed by the video because I know more about engineering. I suppose if you know sod all and are impressed by the voice believe what you like.
No evidence as the demo is NOT connected to the rocket and is 'free flowing' Further more the rocket does not NEED to propel in space because their is no longer any air or gravitation Initial velocity 'U' becomes final velocity 'V' as resistance decreases. As in Newton's Third Law of Motion there is no force acting on the nose of the rocket in space so no EQUILIBRIUM allows the rocket to move forward...simple.
