Pressure at depth 1.6m
= ρgh
= 1000 kg/m³ * 9.8 m/s² * 1.6 m
= 15,680 N/m²
Force = pressure * area
Hydrostatic pressure acts equally in all directions, i.e. downwards and sideways.
That didn't give me the correct answer
What did you get?
Sorry, I didn't read properly.
The question requested absolute pressure, which includes atmospheric pressure, equal to about 103.59 kPa.
Watch out for units when you add hydrostatic pressure in N/m² (=Pa) to atmospheric pressure in kPa.
What is the pressure acting on your body if you dive down to a depth of 3.4 m?
P fluid=r x h x g wher h =3.4m
P total =P atmospheric + P fluid
Normal atmospheric pressure = 1.01 x 10^5
