A cubical box 400.0 Cm on each side is immersed in a fluid. The pressure at the top surface of the box is 115 200 Pa and the pressure on the bottom surface is 132.1 kPa . What is the density of the fluid ?

Answer:

431 kg/m³

Explanation:

Hydrostatic pressure (P) is equal to the density of the fluid (ρ) times the acceleration due to gravity (g) times the depth of the fluid (h).

P = ρgh

ΔP = ρgΔh

132,100 Pa − 115,200 Pa = ρ (9.8 m/s²) (4.00 m)

ρ = 431 kg/m³
