I have a question. We are given an inclined plane with height $h$ and hypotenuse length $d$.

And water is falling down through a hose on the slope. The hose has a inner diameter $l$ and thickness $b$.

Then what value of speed of the water at the bottom of the inclined plane?

I think that this problem perhaps involves Navier-stokes equation and I can't deduce associated formula. Is there an associated data? Where?

Can anyone helps?

    $\begingroup$ It is not clear how hose placed regarding to plane? Is hose over plane or in plane? $\endgroup$ Commented Feb 8, 2022 at 5:48
  • $\begingroup$ Uhm, over plane~ $\endgroup$

    $\begingroup$ Is viscosity considered in this situtation $\endgroup$ Commented Feb 8, 2022 at 7:24
  • $\begingroup$ Yes. If viscosity is also considered, it will be good. $\endgroup$
