increase in pressure
δP = P(2m below) - P(atm)
= ρhg + Patm - Patm
= ρhg
= 1000×2×9.8
= 19600 N\m² or Pa

19600 Pa
Explanation:
- To Calculate increase in pressure at a depth or in other words at the bottom of a liquid, The Formulae used is: P = hdg OR P = hpg.
- In the formulae :
P = stands for Pressure.
h = Stands for Depth.
d Or p (rho) = Stands for density.
And lastly g = stands for gravitational field strength. (which is equal to 9.8 or 10 rounded up.)
- For calculation:-
P = hdg
P = 2 x 9.8 x 1000
P = 19600 Pa
-Why Pascals? Because when Depth (h) is in m and density (p or d) is in kg/m³ Then pressure will be in Pascals (Pa).
Note: I know I made the answer seem long and complicated But To me when I see answers like this, It helps me understand better and so I hope you do too.
