Video is unavailable as a general Youtube outside of the USA. One needs a PBS account, VPN, or some other mystical technological override. Nonetheless, looking it up, button talking dogs seem to be all the rage for some owners to show off how 'smart' their dog is. Their dog is their 'child'? A...

The street Are You Ready For This is the one behind you.

What are the side streets ? This and That would make a lot of sense.

You need the Philosophy of Dilemma for Dummies book.

Darn, My first guess was going to be Batman.

That's going to take me a while, if ever. Lost my illuminati all seeing eyeball.

Mine must be defective, or a fake. It is 26 inches x 42 inches ( and 1/4 inch thick ) Don't tell me I have the Flat Earth rip off.

Was CPM around at that time? Should have had a blue shirt named PIP.

Not to worry. The snail is already home.

@A.T. T Great article, where did you find it. I think a speedup is implied already for flow over an obstacle, such as a building. Somewhere along the lines of a factor of 1.1, more less than more. U∞ would have to be addressed for each and every building, and then find Uref, the velocity at the...

The streamline figures in post 27 can be somewhat deceiving at first glance. The streamline figure spacing is shown compressed, rather than equally spaced, at near y/D = 0 at location x/D = -2 at the left of the figure, with similar streamline compression with x/D increases. The streamlines...

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 by @FactChecker. Below about Mach 3, this form can solve the velocities and pressures from one point to another along a streamline quite adequately for a great...

No. Bernoulli says nothing about a change in temperature. https://efficientengineer.com/bernoulli/

Is this your understanding if flow around a house, building, mostly low rise? The reference given in the post 17 shows that flow around buildings, especially high rise downtown areas, can have complicated air movement patterns. The upwind velocity U profile need not be that as shown in the...
