It is one of the best explanation on the subject, I am a mechanical engineer and an aeronautical engineer plus MBA,with 40 years of experience in MNC ‘S in automaticcontrol systems for crude petroleum refineries,including top American co. I really love your knowledge and your wish to to share your knowledge. You are great,really.Congratulations to you.

Your initial numbers don't compute. If the 20 psi is from twice the mass and the 20 is gauge pressure, the internal absolute pressure should be double. Per PV=nrT, if n doubles then P should double. Therefore, the 20psi gauge is 40 psi absolute. Sea level is only around 14.7, not 20. Do you have that much error?

18:03 and after 18:17 i dont understund this contradiction. At least to me. So i have to add airflow under or above foil/wing to make lift?

10:41 what if you put 2 opening of small area in the size of large opening area? Will augment the trust, in this case will increse the range of water fall?

5 minutes was enough to determine that this is not worth any more of my time. He doesn't realise that a wing does not operate in a tube. Or that his acknowledged concern about the incompressibility of air is indeed a show stopper. Conservation of mass in a tube has absolutely nothing to do with the generation of lift.

This is a terrible take. The first 5 minutes are spent demonstrating that people's knowledge isn't flawed, but rather air can act in different ways in different circumstances. He caps it off by stating that in open circumstances pressure and velocity can adjust to allow density to remain constant, therefore incompressible. Conservation of mass absolutely is applicable to lift generation, as an airfoil relies on it to generate differential velocities and therefore pressures on the upper and lower surfaces, which is the basic principle behind lift generation. I'd genuinely recommend taking another watch, this video is significantly better at explaining the principle, supported by experimentation, than any of my previous education.

@@Polypythat You do yourself no favours by being an apologist for this nonsense. Conservation of mass in an ideal fluid, (incompressible, inviscid etc.) led Bernoulli to his now famous but poorly interpreted principle. Bernoulli's principle states that in a moving fluid, (and he only worked with water) a change in flow rate is always associated with a pressure change. What the principle doesn't say is that a change in pressure in air (the highly compressible form of a fluid) is always associated with a change in flow rate. A change in pressure in air can be associated with a change in flow rate, but a change in pressure in air can also be associated with a change in volume (by evacuation or compression) or a change in temperature. It's a case of A always results in B but B is not always associated with A. All dogs are animals, but not all animals are dogs. A change of pressure in air does not have to be associated with momentum, velocity or acceleration: think about your tyre pump. Think about heating a container.
