Water runs into a fountain, filling all the pipes, at a steady rate of 7.53×10−2 m3/s. How fast will it shoot out of a hole 4.49 cm in diameter? At what speed will it shoot out if the diameter of the hole is three tim

Hot water with a density of 980 kg/m3 flows through a 53 mm diameter round pipe at 1.71 m/s.  What is the mass flow rate (in kg/s) of the water [round your final answer to 2 decimal places]? {Acircle = (π/4)d2}

You want to siphon rainwater and melted snow from the cover of an above-ground swimming pool. The cover is 1 m above the ground. You have a plastic hose of 1.0cm radius with one end in the water on the pool cover and the other end on the ground. (a) At what speed does water exit the hose? (b) If you want to empty the pool cover in half the time, how much wider should the hose be? (c) How much faster does the water flow through this wider pipe?

A thin stream of water flows smoothly from a faucet and falls straight down. At one point, the water is flowing at a speed of v1=1.63 m/s . At a lower point, the diameter of the stream has decreased by a factor of 0.769. What is the vertical distance h between these two points?
