Water at a gauge pressure P₁ at street level (zero, reference height) flows into an office building through a pipe with the radius R₁ of the circular cross-section. The pipe tapers down to the radius R₂ of the circular cross-section by the top floor, located at the height h, where the faucet has been left open. Find the water speed V₂ in the pipe on the top floor in terms of P₁, R₁, R₂, h, water density ρ and g. Assume no branch pipes and ignore viscosity.

A ball of mass M is thrown from the ground at an angle of α from the vertical with a speed S
A ball of mass M is thrown from the ground at an angle of α from the vertical with a speed S. The ball lands on top of a building that height is h. What is the speed of the ball just before it lands on the roof of the building?
