(a) Calculate the absolute pressure at the bottom of a fresh-water lake at a depth of 25.8 m. Assume the density of the water is 1.00 ✕ 103 kg/m3 and the air above is at a pressure of 101.3 kPa. Pa (b) What force is exerted by the water on the window of an underwater vehicle at this depth if the window is circular and has a diameter of 36.0 cm? N
A 5.0kg cube of metal has a density of 3000 kg m3 and is held by a vertical string while immersed in water which has a density of 1000 kg m3 . Assume that the cube is oriented so that all the faces are either vertical or horizontal. a) What is the length of each side of the cube? (b) What is the difference in pressure between the top of the cube and the bottom? (c) What are the vertical...
Two pressure sensors are installed on a 9-meter-high submarine: one sensor is on the top and another one in at the bottom of the submarine. When the submarine dives, what is the difference in readings of the two pressure sensors? The density of water is 1000 kg/m.
3: Water in an hl=17 cm deep pan is observed to boil at 101 C. Assume the saturation pressure is 101 kPa. At what temperature will the water in an h2=87 cm deep pan boil? The water density is 1000 kg/m”. Assume that the temperature difference is approximately proportional to the pressure difference in this region of temperature and pressure: the relationship is dT = 0.23 dp, in which the units of temperature and pressure are K and kPa, respectively....
(5 pts) A pump is pumping water from a lake to the top of a mountain through a constant- diameter pipe. Water exits the pipe at a volumetric flow rate of 0.04 m/s. The vertical distance between the lake surface and the pipe exit at the top of the mountain is 100 m. The diameter of the pipe is 10 cm. All mechanical energy losses are negligible and the flow is steady and incompressible. (Water density-I g/cm, ?-I.) Determine a)...
Water has a density of 1000 kg/m^2. The depth of a swimming pool at the deep end is about 5.0 meters. a. What is the volume of a column of water 5.0 m deep red 0.8 m^2 in cross-sectional area? b. What is the mass of this columns of water? c. What is weight of this column of water in newtons? d. What is the pressure on the bottom of the pool?
4. What is the total force on the bottom of a 2.0-m-diameter by 1.5-m-deep round wading pool due to the weight of the ain and the weight of the water? (Note the pressure contribution from the atmosphere is 1.0 x 10 Nim2, the density of water s 1 000 kg/m3, and g -9.8 m/s2) 9 a. 5.1E+5 N b. 1.4E+6 N c. 2.1E+6 N d. 2.1E+5 N e. 3.6E+5 N We were unable to transcribe this image
a) In the deep space between galaxies, the density of atoms is as low as 106 atoms/m3, and the temperature is a frigid 2.7 K. What is the pressure (in Pa)? (b) What volume (in m3) is occupied by 6 mol of gas? (c) If this volume is a cube, what is the length of its sides in kilometers?
3. (22 points) Consider the tank below with a cylindrical middle and hemispherical bottom and top. Assume that the tank is half full of water. Set up, but DO NOT SOLVE an integral (or integrals) that can be used to determine the work required to pump all of the water out of a spout level with the top of the tank. Note: the density of water is 1000 kg/m3. Make sure to indicate an axis, with 0 marked. In your...
