10) Water circulates throughout an apartment complex in a hot water heating system. (a) If the water is pumped at a speed of 0.50 m/s through a 4.0 cm diameter pipe under a pressure of 3.1 × 105 Pa, what will be the velocity and pressure in a 2.6 cm diameter pipe on the second floor 5.0 m above? (b)If the apartment building is 8 floors total, will there be enough pressure for the water to get to the top floor? Explain your reasoning. (You can assume every floor is 5m and that the pipe size stays 2.6 cm)

A pipe with a radius of 51 cm has water flowing at 5.3 m/s. If water goes into a new pipe with radius 21 cm, how much will the pressure decrease? ΔΡ- unit Pa

When you hold your hands at your sides, you may have noticed that the veins sometimes bulge—the height difference between your heart and your hands produces increased pressure in the veins. The same thing happens in the arteries. Estimate the distance that your hands are below your heart. If the average arterial pressure at your heart is a typical 100 mm Hg, what is the average arterial pressure in your hands when they are held at your side?

the water faucent for a garden hose is tuned on, but with the nozzle turned off the owner of the garden assumes that the water cannot exit the hose. however , even through the hose lies horizonatlly on the ground, the owner notice a stream of water spraying vertically out a small leak in the hose. to a height of 0.75 m. what must be the pressure of the water inside the hose  1) 7.9 kpa 2) 8.8 kpa  3) 7.4 kpa 4) 101.3 pka

In an industrial cooling process, water is circulated through a system. If water is pumped with a speed of 5.20 m/s under a pressure of 5.00*10^5  Pa from the first floor through a 3.80-cm diameter pipe, what will be the pressure on the next floor 3.50 m above in a pipe with a diameter of 3.00 cm?

Fire hoses used in major structure fires have inside diameters of 6.4 cm. Suppose such a hose carries a flow of 40 L/s starting at a gauge pressure of 1.62 × 10°N/m². The hose goes 10 m up a ladder to a nozzle having an inside diameter of 3 cm. Assume negligible resistance, density of water is 1000 kg/m³, and atmospheric pressure = 1.013×105 Pa. Using the flow rate (a) Calculate the velocity at the start of the hose. V = start m/s (b) Calculate the velocity at the nozzle. V = nozzle m/s Pnozzle (c) Calculate the gauge pressure at the nozzle, P, If nozzle <3%, then enter P nozzle =0, else P atm |P nozzlel enter the calculated value. If atm <3%, then we are going to assume that the absolute pressure at the nozzle is approximately equal to the atmospheric pressure, making the gauge pressure almost zero when compared to the atmospheric pressure.
