Question on calculating the pressure outside lungs of diver

In summary, the pressure outside the lungs of a diver can be calculated using the formula P = ρgh and is affected by factors such as depth, water density, and gravity. It increases with depth and is important to calculate for safety reasons. It can be measured using a pressure gauge attached to a diver's equipment.

Given the following information: a 6.10m long snorkel, density of air = 1.21 kg/m^3, atmospheric pressure = 1.013 x 10^5 P, g = 9.8 m/s^2 and density of seawater = 1.03 x 10^3 kg/m^3, how would you calculate the pressure outside the scuba diver's lungs?

Would it be anything to do with this equation?

pressure outside lungs = atmospheric pressure + (density of seawater)*g*(6.10)

Thanks.

hi jayadds! :smile:

(i don't see the relevance of the snorkel, especially since i don't think scuba includes a snorkel :confused:)

that certainly gives the pressure outside his chest :smile:
 

Related to Question on calculating the pressure outside lungs of diver

1. How is pressure calculated outside the lungs of a diver?

The pressure outside the lungs of a diver can be calculated using the formula P = ρgh, where P is the pressure, ρ is the density of the fluid, g is the acceleration due to gravity, and h is the depth of the diver.

2. What factors affect the pressure outside the lungs of a diver?

The pressure outside the lungs of a diver is affected by the depth of the dive, the density of the water, and the acceleration due to gravity.

3. Does the pressure outside the lungs of a diver change at different depths?

Yes, the pressure outside the lungs of a diver increases with depth. For every 33 feet (10 meters) of depth, the pressure increases by about 14.7 pounds per square inch (psi).

4. Why is it important to calculate the pressure outside the lungs of a diver?

Calculating the pressure outside the lungs of a diver is important because it helps determine the potential risks and hazards associated with diving, such as decompression sickness. It also allows divers to plan their dives and make necessary adjustments to their equipment and techniques.

5. How can the pressure outside the lungs of a diver be measured?

The pressure outside the lungs of a diver can be measured using a pressure gauge, which is typically attached to a diver's equipment. This gauge will display the pressure in units of psi or bar, allowing the diver to monitor their depth and adjust accordingly.
