A vertical tube open at the top contains 4.0 cm of oil (density 0.82 g/cm3) floating on 4.8 cm of water. Find the gauge pressure at the bottom of the tube

A liquid is flowing through a horizontal pipe whose radius is 0.0301 m. The pipe bends straight upward through a height of 8.80 m and joins another horizontal pipe whose radius is 0.0726 m. What volume flow rate will keep the pressures in the two horizontal pipes the same? Number Units 202

A liquid-filled tube called a manometer can be used to measure the pressure inside a container by comparing it to the atmospheric pressure and measuring the height of the liquid. Such a device (filled with water) is shown in the figure, measuring the pressure inside a balloon filled with an unknown gas. The water level on the side of the manometer which is open to the air is 22.3 cm higher than on the side connected to the balloon. a) Find the gauge pressure in the balloon, in units of Pa. Recall the density of water is 1000 kg/m3.  b) Find the absolute pressure in the balloon, in units of Pa.

Will the force exerted on the bottom of the tube increase if the diameter (d) of the tube increases and the height of the water column is maintained? 2. Since P = F/A, will increasing the weight of the water in the tube affect the pressure exerted on the bottom of the tube?

A force of 120.0 N is applied to 2.000 cm diameter piston, which is in contact with a closed container of water (density of water = 1,000 kg/m3). A second piston, with a diameter of 25.00 cm and at the same height as the first piston, is also in contact with the water. What force does the water pressure exert on the second piston?   Multiple Choice   10,450 N.   8,450 N.   18,750 N.   9,150 N.   9,500 N.

Water at a pressure of 3.85 x 105 N/m2 at street level flows into an office building at a speed of 0.68 m/s through a pipe with a radius of 2.5 cm. The pipe tapers down to 1.4 cm in diameter by the top floor, 18 m above the street. The flow speed is 2.2 m/s at the top floor. Calculate the pressure in the pipe on the top floor.

A horizontal pipe of cross-sectional area 0.29 m2 at height 6 m carries water at speed 1.9 m/s. The pipe turns upward and levels out again to horizontal at height 14 m, where the pipe narrows to 0.11 m. If the pressure is 202 kPa at the original height, what is the pressure in kPa at the final height? The density of water is 1000 kg/m3. kPa

Water travels through a pipe at 11.1 m/s. The pipe expands from a crossectional area of 1.5 m2 to an area of 12.0 m2. What is the speed of the water in the second part of the pipe in m/s? How much is the pressure change in KPa as the pipe expands? The density of water is 1000 kg/m3. Enter a positive value for an increase in pressure, a negative value for a decrease.

A beaker is filled with an unknown liquid up to a depth of 10.00cm . The gauge pressure at the bottom of the beaker is measured to be 1540.00Pa . What is the density of the liquid contained in the beaker?
