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?
