Question

Knowing that the pressure on the surface of a lake is 1 atm, at what depth is the pressure triple? please help

Answer 1

20 m

Step-by-step explanation:

1 atm = 101325 Pa

The absolute pressure at a depth of h is:

P = Patm + ρgh

3 (101325 Pa) = 101325 Pa + (1000 kg/m³) (10 m/s²) h

h ≈ 20 m
