What is the pressure on a swimmer 10 m below the surface of a lake?

Explanation

Here
h=10m and `p=1000 kg m^-3` take `g=10 ms^-2`
`P=P_a+pgh`
`=1.01 times 10^5 Pa+1000 kg m^-3 times 10 ms^-2 times 10m`
`approx 2 atm`
This is a 100% increase in pressure from surface level. At a depth of 1km, the increase in pressure is 100 atm Submarines are designed to withstand such enormous pressures.
