What is the pressure on a swimmer 10m below the surface of lake? `g=10ms^(-2)`, atmospheric pressure = `1.01 xx 10^(5)Pa`

Text Solution

Verified by Experts

Given, h=10 m
Density of water, `p=1000 "kg/m"^(3)`
`g=9.8 "m/s"^(2)`
Preesure on a swimmer at a depth of 10m below the surface of the lake,
`P=P_(a)+hpg`
where `P_(a)="atmospheric pressure"`
`=1.013 xx 10^(5)Pa`
`P=1.013 xx 10^(5) +10 xx 1000 xx 9.8 `
`=1.993 xx 10^(5)Pa`
=2 atm
