FactChecker replied to the thread Can a flow created by a fan show an Edge effect when hitting a wall?.There are other things going on. Please try to understand Bernoulli's equation, which gives the trade-off between pressure and velocity. -
FactChecker replied to the thread Can a flow created by a fan show an Edge effect when hitting a wall?.Yes. So that is where the velocity can come from -- decreased pressure. This just means that the random directional movement of atoms... -
FactChecker replied to the thread Can a flow created by a fan show an Edge effect when hitting a wall?.Sorry. I stand corrected. I was thinking about incompressible fluid flow. Thanks. -

I don't think that's the right interpretation. The flow-speed plots in fig. 6 of my post #26 show lower speeds (blue) everywhere around... -
FactChecker replied to the thread Undergrad Light clock treating horizontal and vertical motion differently?.I disagree. IMO, most of the explanations compare a "stationary" light clock to a "moving" light clock. The experimental result that the... -
FactChecker replied to the thread Can a flow created by a fan show an Edge effect when hitting a wall?.Good point. I think that is the unexpressed question of the OP. The diagrams that @renormalize included in post #27 seems to indicate... -

Please look at the standard form of Bernoulli's equation @FactChecker provided and tell us what you see the answer is. You've been... -

Informative.
The Bernouilli equation that one mostly sees, and the one that is presented as an introduction to fluid flow, is of the form in post 42... -
FactChecker replied to the thread Can a flow created by a fan show an Edge effect when hitting a wall?.That is a consequence in certain situations of Bernoulli's equation. It is not Bernoulli's equation. -

Doesn't this come from the series being finite binary expansion? Being finite it will sum to a finite number. -
FactChecker replied to the thread Undergrad Computable sequence of rationals with a noncomputable limit.You should describe ##D## for us, I assume it is a subset of the natural numbers. With that in mind: Since ##f## is an injection on a... -
FactChecker replied to the thread Can a flow created by a fan show an Edge effect when hitting a wall?.It does seem clear from the diagrams @renormalize put in post #27, that the leading corners squeeze the streamlines together. That... -
