how far can a diver, using a snorkel for breathing, can swim in salt water?
The human lungs can function satisfactory up to a limit where the pressure difference between the outside and inside of the lungs is one-twentieth of an atmosphere, if a diver uses a snorkel for breathing, how far below the water can she swim? Assume the diver is in salt water whose density is 1025kg/m^3.
it all depends on the Persons Lung Capacity
but as u get deeper under water the preasure from the water on your lungs causes ur lungs to become smaller and also compresses the air that is in ur lungs so the deeper u go the less Oxygen u will have in ur lungs
in Salt water the Pressure is alot Greater as U get deeper compared to when you in Fresh Water
also considering that when you use a Snorkel you are also not taking in a full breath of air as there is still a remainder of carbon dioxide in the snorkel Tube itself so it would actually be better to take a proper breath than to breath through a Snorkel
P.s Snorkels were Made for Surface Diving
dont think i was much Help Just spilling out the Info i Know

competative divers have been recorded going well over 100 ft down, I dont know how my ears heart at around 20 feet. But I dont know what the world record is

There is really no set number, it depends on conditioning. The captain of our sailing cruise free dived to 60 feet to find lobsters in the Carribean. I can make it to 30 feet, others have set great records by using weights to go down, then swim up. I am sure the record free dive is a couple hundred feet. When I use a snorkel I float just at the surface.

For a depth h below the surface the pressure felt will be
P = P_atm + density*g*h
We want density*g*h = P_atm/20
h = P_atm/(20*density*g) = 10^5/(20*1025*9.8)
h = 0.5 m
This answer fits with the fact that most snorkellers swim just under the surface.

as far as i know an experienced diver with snorkel can go as far as 30-35 meters in salt water.
