russ_watters replied to the thread Can a flow created by a fan show an Edge effect when hitting a wall?.For both videos, please give me the timestamp where they say "Edge Effect". I'm not going to go through them looking for it. -
russ_watters replied to the thread Can a flow created by a fan show an Edge effect when hitting a wall?.Really oddly put when you add "when the fan is switched on", but no, the airflow slows down as it approaches and goes around the plate...

russ_watters replied to the thread Can a flow created by a fan show an Edge effect when hitting a wall?.Is "edge effect" even a real term of art in fluids? Googling it, the only top, relevant hit I get for it is this thread. Got a source...

Like.
He did? Who? Where? -
russ_watters replied to the thread Why is it not allowed to question General Relativity?.Einstein was taken seriously because he was a PhD physicist - that's normal, not rare. His day job at the time is a red herring.

russ_watters reacted to DaveE's post in the thread Why is it not allowed to question General Relativity? with Like.
Physicists already know that GR doesn't work with Quantum Mechanics. It isn't 100% correct. Many are trying to figure this out. So, it's...

No, we do not. Are you suggesting that a sharp corner or edge will provide a source of eddies, because some corner is not sufficiently...

russ_watters reacted to renormalize's post in the thread High School Fan is pushing in the front and sucking from the back with Like.
@Herman Trivilino, do you disagree with the illustration? It clearly depicts the fluid to be flowing through the ear tube in order to...

russ_watters replied to the thread A practical way to vaporize fuel for high MPG?.Right, this thread is about how much power it takes to move a car, not where the "fuel" came from. But I agree we need a clean grid...

russ_watters reacted to Averagesupernova's post in the thread Piston suction pump versus external gear pump as vacuum pump with Like.
If you are just comparing pumps to see which can achieve the highest vacuum I don't see why you even need a vacuum vessel. A hose with a...

russ_watters reacted to jrmichler's post in the thread Piston suction pump versus external gear pump as vacuum pump with Like.
The best vacuum pump depends on your needs. You need to specify two things - the amount of vacuum and the flow rate before we can give...

You just don't get it. Rotary lobe pumps move a lot of air. One place they are used is to move dry granular material. The dry material...

And back to my reply that the question is not answerable with any degree of reliability. - Example: I have a very large vessel to...

Pick them to do what? Many pertinent questions were asked and you have not answered. I suspect you don't really know what you need. You...

Rotary lobe pumps typically used as superchargers have similarities to gear pumps. They are mostly used for non-liquids. I guess it...
