A spherical vessel used for deep-sea exploration has a radius of 1.52 m and a mass of 1.16 104 kg. To dive, the vessel takes on mass in the form of sea water. Determine the amount of mass that the vessel must take on if it is to descend at a constant speed of 1.10 m/s, when the resistive force on it is 1099 N in the upward direction. The density of seawater is 1.03 103 kg/m3. kg

An atmospheric diving suit can be used for very deep dives of up 700 m under the sea level. Calculate the pressure experienced by the suit at this depth (note: the atmospheric pressure on Earth at the sea level P0= 1.01 x105 Pa ; density of water = 1000 kg/m3) Select one: a. 5.49 x 105 Pa b. 6.96 x 106 Pa c. 8.11 x 107 Pa d. 1.33 x 108 Pa e. None of the above

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.

hi, we got this question in a fluid mechanics MCQ : how deep does a swimmer need to go for the pressure exerted on her to double from 1.0 atm experienced at the surface to 2.0 atm? take the density of seawater to be 1050 kg/m^3, and 1 atm= 1.0 × 10^5 pascals. I used P=Po(atmospheric pressure in Pa) +density×gravity(9.81) ×depth, substituted P by 2xPo in Pa and g by 9.81, and rearranged to solve for the depth, for which...

Question 2. Deep sea drones are used to explore the bottom of the ocean. The drone is allowed to sink using its weight force, however if the drone hits the ocean floor with a high velocity the operational camera will break. Hence the velocity of the sinking drone should be less than 4 m/s when hitting the ocean floor. The weight force is countered by drag and buoyancy (See Figure 1). Drag is directly proportional to velocity i.e. D =...

PRACTICE IT Use the worked example above to help you solve this problem. In a huge oil tanker, salt water has flooded an oil tank to a depth of h2-5.40 m. On top of the water is a layer of oil - 8.40 m deep, as in the cross-sectional view of the tank as shown in the figure. The oil has a density of 0.700 g/cm. Find the pressure at the bottom of the tank. (Take 1,025 kg/m as the...

A scuba diver must decompress after a deep dive to allow excess nitrogen to exit safely from his bloodstream. The length of time required for decompression depends on the total change in pressure that the diver experienced. Find this total change in pressure for a diver who starts at a depth of d = 20.7 m in the ocean (density of seawater = 1024 kg/m3) and then travels aboard a small plane (with an unpressurized cabin) that rises to an...

1. A submarine dives from the surface of the ocean to a depth of 3500 feet ( 1foot= 0.305 meters) . a) what pressure increase does the submarine experience? b) at this depth of 3500 feet, what is the force (in units of N) on the hatch which has an area of 0.6 m2 ? Take the density of sea water to be 1030 kg/m3 ( It is a good assumption to presume that sea water has essentially constant density,...
