Water has a density of 1000 kg/m3. The pressure of the atmosphere is 1x105 Pa. Approximately what distance below the surface of a lake is the total pressure three times the atmospheric pressure at the surface? -20 m -30 m -300 m -200 m
A swimming pool of depth 2.7 m is filled with ordinary (pure) water (ρ = 1000 kg/m3). (a) What is the pressure at the bottom of the pool? Pa (b) When the pool is filled with salt water, the pressure changes by 4.5 103 Pa. What is the difference between the density of the salt water and the density of pure water? kg/m3
Ideal Fluid - The Ocean. Water is much less compressible than air. This means that the density of water (~1gm/cm3 or 1000 kg/m3) does not change very much with increasing pressure. This means that as you go deeper in the ocean the mass of water above you is just proportional to depth that you descend. Assuming that you can neglect the small change in gravitational acceleration with depth, show (so that a non-science major friend could follow - do not...
A swimming pool of depth 2.5 m is filled with ordinary (pure) water (ρ = 1000 kg/m3). (a) What is the pressure at the bottom of the pool? 1.2550×105 Pa (b) When the pool is filled with salt water, the pressure at the bottom changes by 5.2 x103Pa. What is the magnitude of the difference between the density of the salt water and the density of pure water? Please show your work :)
A fish swims at 20 m of depth from water surface. The density of water is 1000 kg/ m3, the acceleration due to gravity is 10 m/s2 , and the atmospheric pressure is 105 N/m2. Fluid pressure at the depth 20 *:m is N/m2
Qi (8 pts) Tank in fig below is used to pressurize fertilizer solution (ρ 1000 kg/m3, g-10 m/g2) for spraying. The tank pressure above liquid surface (1) is 30 kPa gage. Height of liquid h 0.8 m. The velocity (m/s) at the outlet (2) (exposed to atmosphere) is closest to: (a) 5.5 (b) 7 (c) 8.7 (d) 15
A block of material with a density of 856 kg/m3 is floating in a fluid that has a density of 1095 kg/m3. What fraction of the object is above the surface of the fluid?
The sperm whale can dive to a depth of 2250 meters. For sea water with a density of 1020 kg/m3 what is the difference in pressure at this depth as compared to the surface? Supply your answer in atmospheres" (atm), where 1 atm approximately equals 1x105 Pa. (This is an incredibly large pressure. Human bodies would be crushed. The deepest human dive recorded was around 300 m, and even then, the diver had to spend 12 hours to surface from...
Water (ρ-1000 kg/m3) flows in a rectangular channel over the 1 m drop. If the width of the channel is 1.5 m, determine the volumetric flow rate in the channel. Assume water is an ideal fluid. 0.5 m 1 m 2 m Figure 3
