Answer Happy

The extremity of a tube, who has a circular section S1 of radius
r1, is raised at a height h=1 meter from the ground. From the
end of the tube, who has a circular section S2 of radius r2=r1/3,
water exits horizontally with flow velocity v2 and falls in
the center of a cilindric recipient, at distance d=5 meters.
The cilindric recipient has a radius R=0.5 meters and the level of
water raises at velocity of 0.5cm/s.
Compute:
- in S1: flow speed v1=? and pression p1?
- in S2: flow speed v2=? and radius r2=?
