Water at a gauge pressure of 3.8 atm at street level flows into an office building at a speed of 0.06 m/s through a pipe 5.0 cm in diameter. The pipes taper down to 2.6 cm in diameter by the top floor, 20 m above. Calculate the flow velocity and the gauge pressure in such a pipe on the top floor.

Water at a pressure of 4.60 atm at street level flows into an office building at a speed of 0.55 m/s through a pipe 4.80 cm in diameter. The pipes taper down to 2.50 cm in diameter by the top floor, 25.0 m above. Calculate the water pressure in such a pipe on the top floor.

Water enters a house from a ground pipe with an inside diameter of 0.02m at an absolute pressure of 4.0 x 105 Pa. A pipe that is 0.01 m in diameterleads to the second-floor bathroom 5.0m above the ground floor. The flowspeed at the ground pipe is 1.5 m/s. Find the following:(a) flow speed on the second floor; and(b) pressure.

Suppose you have a 8.8 cm diameter fire hose with a 3.6 cm diameter nozzle. a) Calculate the pressure drop due to the Bernoulli effect as water enters the nozzle from the hose at the rate of 40.0 L/s. Take 1.00 × 103 kg/m3 for the density of the water. b) To what maximum height, in meters, above the nozzle can this water rise? (The actual height will be significantly smaller due to air resistance.

A negative gauge pressure of 20.5 atm can sometimes be achieved with the device in the figure before the water separates. To what height, in meters, could such a negative gauge pressure raise water?

Water at a pressure of 3.85 x 105 N/m2 at street level flows into an office building at a speed of 0.68 m/s through a pipe with a radius of 2.5 cm. The pipe tapers down to 1.4 cm in diameter by the top floor, 18 m above the street. The flow speed is 2.2 m/s at the top floor. Calculate the pressure in the pipe on the top floor.
