A diver accustomed to standard snorkel tubing of length 25 cm tries a self-made tube of length 8.6 m. During the attempt, what is the pressure difference (in kPa) between the external pressure on the diver's chest and the air pressure in the diver's lungs?

Question

I've been trying to figure it by pascal's law somehow but it doesn't seem to be working for me. Help?

Answer 1

you can use the density of water and the depth to find the pressure

the "rule of thumb" for diving is one atmosphere for every ten meters of depth

Answer 2

Thanks!!
