(a) At one point in a pipeline the water's speed is 3.00 m/s and the gauge pressure is 5.00 • 104 Pa. Find the gauge pressure at a second point in the line, 11.0 m lower than the first, if the pipe diameter at the second point is twice that at the first. Note: density of water is 1000 kg/m3. (b) If the gauge pressure at the second point is half of what you found in part (a), calculate how much energy was lost to friction.

(b) Water enters a house through a pipe with an inside diameter of 2.0 cm at an absolute pressure of 4.x 105 Pascal (about 4 atm). A 1.0-cm- diameter pipe leads to the second-floor bathroom 5.0 m above. When the flow speed at the inlet pipe is 1.5 m/s find, the flow speed and pressure in the bathroom.

The main water line enters a house on the first floor. The line has a gauge pressure of 1.90X10 5 Pa. (a)A faucet on the second floor, 6.50 m above the first floor, is turned off. What is the gauge pressure at hisfaucet? How high could a faucet be before no water would flow from it, even if the faucet were open?

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.

At a certain point in a horizontal pipeline, the water's speed is 2.50m/s, and the gauge pressure is 1.80×104 Pa. Find the gauge pressure at a second point in the line if the cross-section area at the second point is twice that at the first.

At one point in a pipeline the water's speed is 3.00 m/s and the gauge pressure is 5.00×104 Pa. Find the gauge pressure at a second point in the line, 11.0 m lower than the first, if the pipe diameter at the second point is twice that at the first.

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.

(a) At one point in a pipeline the water’s speed is 3.00 m/s and the gauge pressure is 5.00∙104 Pa. Find the gauge pressure at a second point in the line, 11.0 m lower than the first, if the pipe diameter at the second point is twice that at the first.  Note: density of water is 1000 kg/m3. (b) If the gauge pressure at the second point is half of what you found in part (a), calculate how much energy was lost to friction.

A factory is supplied with water through a main pipe with An 8.00 cm diameter. A faucet located h = 1.90 m above the main pipe is 2.00 cm in diameter and can fill a 25.0 L container is 30.0 s. (a) What is the speed (in m/s) at which the water leaves the faucet (in m/s)?   (b) What is the gauge pressure (in Pa) in the 8.00 cm wide main pipe? (Assume the faucet is the only "leak" in the building.)

Water towers store water above the level of consumers for times of heavy use, eliminating the need for high-speed pumps. How high (in m) above a user must the water level be to create a gauge pressure of 3.84 ✕ 105 N/m2?
