10. In an industrial cooling process, water is circulated through a system. If water is pumped with a speed of 6.00 m/s under a pressure of 5.50 x 10° Pa from the first floor through a 3.60-cm diameter pipe, what will be the pressure on the next floor 4.50 m above in a pipe with a diameter of 2.40 cm? Pa sf60 ssfo f60 ssf ssf60 sf60 s

A water cannon 2.15 m long and with a cross-sectional area of 11.0 cm2 is aimed straight up and ejects water out of the top at a speed of 8.8 m/s. It is fed by a pump at the bottom of the cannon, which has a cross-sectional area of 46.0 cm2. What is the difference in pressure of the water between the pump and the top of the cannon? Assume the density of the water is 998.2 kg/m3.

Water is flowing without friction through a pipe. At the beginning of the pipe the water is flowing with a speed of 2.42 m/s, while at the end of the pipe the water is flowing at 5.74 m/s. The end of the pipe is higher than the beginning of the pipe. If the pressure is 60.8 kPa at the beginning of the pipe and 8.00 kPa at the end of the pipe, how much higher is the end of the pipe from the beginning of the pipe?

A friend asks you how much pressure is in your car tires.  Unfortunately, you have misplaced your gauge but confident in your knowledge of physics you tell your friend “I can figure it out”.  From the owner’s manual you find that the car’s mass is 1450 kg and that the tire manufacturer recommends 32 psi.  Assuming that each tire supports one-fourth of the weight of the car, you use a ruler to find that the tires are 15 cm wide and the flattened segment of the tire in contact with the road is 16 cm long.  What answer do you give your friend? Express your answers in pounds per square inch (psi)

Water is circulating through a closed system of pipes in a two-floor apartment. On the first floor, the water has a gauge pressure of 3.1 105 Pa and a speed of 2.4 m/s. However, on the second floor, which is 3.8 m higher, the speed of the water is 3.6 m/s. The speeds are different because the pipe diameters are different. What is the gauge pressure of the water on the second floor? Number Units. Pa

Question 7 of 18 You come across an open container that is filled with two liquids. Since the two liquids have different densities, there is a distinct separation between them. Water, which has a density of pw = 1.00 × 10³ kg/m³, fills the lower portion of the container to a depth of 0.200 m. The fluid that is floating on top of the water is 0.307 m deep. If the absolute pressure on the bottom of the container is 1.049 × 10° Pa, what is the density, pi, of the unknown fluid? The acceleration due to gravity is g = 9.81 m/s² and atmospheric pressure is Po = 1.013 x 10° Pa. Pi = kg/m3

A fluid with density 1200 kg/m flows through this pipe. As the first location, A, the fluid travels at 7.5 m/s and at the second location, B, the fluid travels at 11 m/s. What is the difference in pressure between the two points? O-1.9 x 10 Pa +3.8 x 103 Pa -2.5 x 104 Pa -3.9 x 10 Pa O +5.0 x 104 Pa

3. In scuba diving, a regulator is used so that the pressure of the air the diver breathes is close to that of the ambient water. A reckless swimmer decides to use a hose sticking out of the surface to breathe underwater while diving in a lake. When the air pressure in the lungs is at a pressure of around 0.155 atmospheres below the ambient pressure, lung injury may occur. Find the depth at which the swimmer would experience such a pressure differential.

Jody rests her full coffee cup on the table. The full cup has a mass of 680 grams, and the area of the bottom of the cup is 0.0065 m^2. What pressure is the full cup exerting on the table?   220 Pa   105 Pa   1030 Pa   1.04∗10^5 Pa
