Q2. A "U" shaped tube (with a constant radius) is filled with water and oil as shown. The water is a height hi = 0.400 m above the bottom of the tube on the left side of the tube and a height h2 = 0.250 m above the bottom of the tube on the right side of the tube. The oil is a height h3 = 0.300 m above the water. Around the tube the atmospheric pressure is PA = 1.00×105 Pa. Water has a density of 1000 kg/m³. Clearly show all work! a) What is the pressure in the water at the bottom of the tube? T b) What is the pressure in the water right at the oil-water interface? h₁ h₂ h₂

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 U shaped tube with diameter 2.00 cm, open to the air on both ends, contains mercury. Oil ispoured into the left arm until the oil column is 15.0 cm high. Then water is poured into the rightarm until the water column is 10.0 cm.a. On which side of the tube is the mercury level higher? Support your answer.b. What is the change in height of the mercury on both sides of the tube?c. To make the mercury return to its original level, which fluid would you have to add to thetube, and how much would you have to add (in cm cubed)?

A raft has dimensions 7.0 m x 7.0 m with a thickness of 1.0 m and made of material with average density 650 kg/m3.    a. When floating in water, what percentage of the volume is under water?   b. What is the pressure underneath the raft?   c. How heavy of a load is necessary to cause the raft to be 80% submerged in water?   d. If the raft is made with a different material of lower density and 80% of it is still submerged, how if at all would your answers to (a), (b) and (c) change?   e. , explain how, if at all, the answer to (b) is related to the buoyant force. f. Imagine that the load increases enough to fully submerge and then sinks the raft to the bottom of the lake.  How, if at all, does the buoyant force vary during this process?

The same fluid (density unknown) fills three depressions on an alien planet. Depression #1 is a small pond. Depression #2 is a large lake. Depression #3 is a very large ocean. All of these depressions have the same depth. Gravity g is the same at all three locations. However the value of gravity is unknown. How do the gauge pressures at the bottoms of the three depressions compare?   A. P3 > P2 > P1   B. They are the same   C. P1 > P2 > P3   D. Can't tell without knowing the dimensions of the depressions.

Ethanol is flowing in a pipe and at all points completely fills the pipe. At point A in the pipe the gauge pressure is p and the cross-sectional area of the pipe is 0.0500 m² . The other end of the pipe (point B) is open to the air, has cross-sectional area 0.0120 m2, and is at a vertical height of 9.00 m above point A. Part A What must the gauge pressure p be at A if the volume flow rate out of the pipe at point B is 0.0800 m /s? Express your answer with the appropriate units.
