A water barometer is used to measure air pressure in a duct where the air is being forced to ventilate a building. One end of the barometer is open to the atmosphere, and the other end is open to the inside of the ductwork. When the tube is bent in the shape of a U, the technician notes that the water level on the side toward the duct is lower than the side toward the atmosphere by 13.4 cm. What is the pressure difference in N/m2? The density of water is 1 gm/cm3 or 1000 kg/m3. Use 9.8 m/s2 for the acceleration of gravity.
A popular pool toy allows the user to push a plunger to compress water in a barrel with a diameter of 3.5 cm. The water is compressed with a speed of 1.9 m/s and emerges from a small opening with a speed of 12 m/s. What is the diameter (in mm) of the opening? Assume the toy is oriented horizontally. mm
Problem 3: Water flows through a horizontal cylindrical pipe from a smaller-diameter region to a larger-diameter region. At point A, where the pipe's diameter is 3.5 cm, the water's speed at 25.0 m/s. At point B, the pipe's diameter is 7.0 cm. (a) What is the water's speed at point B? (b) What is the pressure difference between points A and B? Which point has the greater pressure?
Water flows at a speed of 2.8 m/s through a 9 cm diameter pipe to a 4.5 cm diameter pipe. What is the speed of the water in the 4.5 cm diameter pipe?
For its drinking water, a small cabin in the woods uses a sealed water tank. The tank is filled to a depth of 1.89 m and then a small air pump can be used to pressurize the pocket of air above the water. Water flows out from the bottom of the tank through a small hole. What is the speed of water when it exits the tank if the air is pressurized to a gauge pressure of 2.05 atm? Give your answer in units of m/s.
A liquid of density 1374 kg/m3 flows with speed 1.02 m/s into a pipe of diameter 0.18 m. The diameter of the pipe decreases to 0.05 m at its exit end. The exit end of the pipe is 8.95 m lower than the entrance of the pipe, and the pressure at the exit of the pipe is 1.1 atm. 1.1 atm W 1.02 m/s 0.18 m 8.95 m 0.05 m Applying Bernoulli's principle, what is the pressure P at the entrance end of the pipe? Assume the viscosity of the fluid is negligible and the fluid is incompressible. The acceleration of gravity is 9.8 m/s² and Patm 1.013 x 105 Pa. Answer in units of 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?

A tank holds a large amount of water. A pipe is connected to the tank at the upper end and is open to the air at the lower end (see figure).The upper end of the pipe has a diameter of 17.0 cm. The lower end of the pipe has a diameter of 8.60 cm. The speed of the water at the upper end is 2.00 m/s.What is the flow rate of the water in the pipe?
A container with water is pressurized and attached to a hose. The pressure inside the container, P, is set so that when the end of the tube is 4.5 meters above the water level in the container is ejected at 3.5 m/s. The reservoir in the container is large enough that you can ignore the change in height of the water in the container. What is the pressure P in atmospheres?
