2. A large bottle contains 350 L of water, and is open to the atmosphere. If the bottle has a flat bottom with an area of 2 ft2, calculate the absolute pressure at the bottom of the bottle. Give your answer in Pa. Assume the water has a density of 1000 kg/m and assume the system is at sea level on Earth. Answer: over 100,000 Pa
Normal Atmospheric Pressure is 101, 300 Pa. Oil floats on water. Below, is shown an open tank with a layer of oil (density 850 kg/m^3) on top of a layer of sea water (1030 kg/m^3) Calculate in each case the Absolute pressure at: (Shown on setup) Level 1: (al top of lank) _______________ Level 2: (at interface of oil and seawater) _______________ Level 3: (at bottom of tank) _______________
An enclosed tank containing water of density (r = 1000 kg/m3) has a hole in its side at a distance y1 from the tank’s bottom as shown in figure. The hole is open to atmosphere (Po = 1´105 Pa) , and its diameter is much smaller than the diameter of the tank. The air above the liquid is maintained at a pressure (P = 1.6´105 Pa). Determine the speed of the liquid as it leaves the hole when the liquid’s...
One end of a U-tube that contains water is open to the atmosphere but the other end is closed. When some air is trapped in the closed end, the difference in the height of the water, h, is 14 .0 cm. Assume the outside air pressure is 0.9600 atm. A) What is the gauge pressure of the trapped air? B) What is the absolute pressure of the trapped air?
(a) A large, open at the top, upright cylindrical tank contains a brine with a density of 1.23 x 103 kg/m. If the air pressure is 101.3 kPa, determine the absolute pressure (in Pa) in the fluid at a depth of 27.0 m. 1269.16 The absolute pressure at any point in the fluid is the sum of atmospheric pressure and the pressure due to the depth of the fluid. How can you account for the pressure due to the depth...
(a) A large, open at the top, upright cylindrical tank contains fuel oil with a density of 0.890 x 103 kg/m². If the air pressure is 101.3 kPa, determine the absolute pressure (in Pa) in the fluid at a depth of 32.5 m. 283465x The absolute pressure at any point in the fluid is the sum of atmospheric pressure and the pressure due to the depth of the fluid. Did you remember to account for atmospheric pressure? Pa (b) Determine...
A container is filled to a depth of 0.805m with water. On top of the water floats a 1.66m-thick layer of oil with density 700kg/m^3. What is the absolute pressure at the bottom of the container if the whole thing is placed in ordinary atmosphere at sea level? Give your answer in units of atm.
A graduated cylinder contains a 0.6 m column of water (density 1000 kg/m3) and a 0.1 m column of oil (density 850 kg/m3), which rests on top of the water column. The test tube is open to the atmosphere (Patm=101,300 Pa). What is the pressure at the midpoint in the water column (point P)?
A tall storage tank contains liquid water at 17.5oC and is vented to atmosphere at the top (where atmospheric pressure = 760mm Hg). The distance from the bottom of the tank to the liquid surface level is 8.0 m. What will be the absolute pressure at the bottom of the tank?
11: In the picture below, the top of the manometer tube is open to the atmosphere. Liquid mercury has a density of 13,500 kg/m . The height difference between the two mercury levels is 0.20 m. A) What is the gauge pressure of the gas in the bulb in Pa and is it over or under the regular atmospheric pressure? B) What is the absolute pressure of the gas in the bulb in atmospheres? Gas Liquid Mercury 0 0 B
