##\Delta s## also tends to zero, as ##\Delta t## tends to zero. The limit can be finite in that case. A purely mathematical example...

How does this oppose the fact that pressure of water in pool at certain depth will be equal to the sum of static (atmospheric) and...

I’m kinda confused now. What exactly did I say wrong? Also, by specific volume, do you mean just volume of the fluid?

All the equations you have written are the incompressible case.

So? Aren’t we talking about the incompressible case?

If that’s the case, why do we use this formula for pressure of water inside some container: ##p = p_0 + \rho g h## Where the second...

We consider water to be incompressible ideal fluid here. The hydrostatic pressure as I stated in equation varies with depth only. Also I...

No, I didn’t say that. I said they are two independent and very much different pressures. I said static pressure is basically pressure...

Hydrostatic pressure is simply pressure exerted by the weight of fluid molecules (so it’s usually ignored in gases). However, static...

Yes. It is (in normal circumstances) as large as it needs to be to prevent the bodies from interpenetrating.

Yes I understand that about Newton’s third law. I might have formulated it poorly. Force exerted by the ball acts perpendicular to the...

Yes. A simple model of a ball hitting a wall is a point mass and a spring. The spring contacts the wall, compresses, and pushes the...
