What is the total pressure on a diver at 99 feet below the surface how many units?
At 99 feet below the surface, the total pressure on a diver can be calculated using the formula: total pressure = atmospheric pressure + (depth in feet × 0.433 psi/ft). The atmospheric pressure at sea level is approximately 14.7 psi. Thus, the total pressure at 99 feet is about 14.7 psi + (99 ft × 0.433 psi/ft) = approximately 14.7 psi + 42.8 psi = 57.5 psi. Therefore, the total pressure on a diver at that depth is approximately 57.5 psi.

What is the expected pressure of air in lungs of a diver at 4 meters below the sea level?
Air pressure (at sea level) is about 1 bar; every 10 meters below the water surface, pressure increases by about 1 bar - that gives a total of 1 + 0.4 = 1.4 bar. (1 bar is about 1 atmosphere.)
What partial pressure of oxygen is a scuba diver breathing if the total pressure is 6.3 ATM and 20 percent of the air is oxygen?
The partial pressure of oxygen can be calculated by multiplying the percentage of oxygen in the air by the total pressure. In this case, 20 percent of 6.3 ATM is 1.26 ATM. Therefore, the scuba diver is breathing oxygen at a partial pressure of 1.26 ATM.
About What fraction of atmospheric pressure greatest at the surface of earth?
At the surface of the Earth, about 99% of the atmosphere's total mass is located below 32 km. This is where most of the atmospheric pressure is concentrated. Therefore, the greatest fraction of atmospheric pressure is present at the Earth's surface.
If there is a total of one liter of nitrogen gas dissolved in the body tissue at sea level how much would be dissolved in a diver breathing air at 99 feet below the sea a?
4 litres. 99 Feet is approx 30 mts. For every 10 mtrs you are 1 atmosphere pressure than the surface so you are at 4 times the surface. So 4 litres.

Industrial deep-sea divers must breathe a mixture of helium and oxygen to prevent a disorienting condition known as nitrogen narcosis. If a diver's tank is filled with a helium-oxygen mixture to a pressure of 170 atmospheres and the partial pressure of helium is 110 atmospheres, the partial pressure of the oxygen is ? - is the question The answer is 60. Total pressure minus the partial pressure= 170-110= 60.
How much preasser is gravity?
The pressure of gravity on a surface is(total force of gravity on the surface) divided by (area of the surface)
Does the evaporation in the evaporation column influence the total pressure?
evaporation as such influence on the total pressure. evaporation occurs when the total pressure is greater than the surface molecules vapour pressure. as the rate of evaporation increases , more vapour will be there at the top, and then the new total pressure will become the sum of the earlier total pressure and vapour pressure of the vapour evaporated. hence total pressure increases.............

How much pressure is on a diver at 1000ft deph?
At a depth of 1,000 feet (approximately 305 meters) underwater, the pressure exerted on a diver is about 30 times greater than at sea level. This means the total pressure at that depth is roughly 30 atmospheres or 4,500 psi (pounds per square inch). The increased pressure is due to the weight of the water above the diver, which adds significant stress on the body and equipment. Divers at this depth require specialized training and equipment to safely manage the extreme conditions.
How will pressure of an object will change if its area is doubled?
It won't. The pressure within a hollow object may change if the surface area changes, hence the volume. The total pressure acting on the exterior of a solid object may change if the total surface area changes.
How will the pressure of an object change if area is doubled?
It won't. The pressure within a hollow object may change if the surface area changes, hence the volume. The total pressure acting on the exterior of a solid object may change if the total surface area changes.
Why is air that is pressurized needed in scuba diving?
The pressure on a diver's body increases quickly with depth. At the surface we're all breathing air at 14.7 PSIg, or 1 "Atmosphere" (atm). Each 33 feet of sea water results in another 1 atm of pressure. This means, for example, that a diver's body is under a total pressure of 3 atmospheres at 66 feet of sea water (one of air, two of water). The human respiratory system is designed to operate at normal atmospheric pressure of 14.7 pounds per square inch. If we descend to 33 feet, the water pressure exerts a force of nearly 30 pounds per square inch on our bodies. Our bodies are incapable of breathing against that much pressure. A scuba pressure regulator is designed to deliver air at the same pressure as the surrounding water, allowing us to breathe.
