Water flows througn a pipe of varying diameter, as shown in figure below. If area 1 (A1) = 8 cm2, A2 2 cm2 and the speed of water in pipe 2 v2 2 m/s then what is the speed of water in pipe 1 v1. %3D %3!

Water enters a fountain through a pipe with a cross-sectional area A₁ at a flowrate Q. The pressure in the inlet pipe is p₁. The water then leaves through a nozzle with a cross- sectional area A2 and at an angle 0, as shown in Figure Q5. Both the inlet and the nozzle are at a height h2, and the jet reaches a maximum height h3. X You may assume that viscosity is negligible. a) Find the horizontal force on the block b) What is the horizontal-component (u₂), vertical component (v₂) and magnitude (V₂) of the velocity of the jet as it leaves the nozzle? = c) What is the maximum height of the jet? You may assume that the horiztonal component of velocity is the same at every point in the jet.

How do I answer this question?

plzzzz help meeeeee right nowwwww
