Please calculate using Pascal's law. The window of the diving helmet has a surface content of about 7dm2. Calculate what pressure force acts on the window at a depth of 20 meters below the water surface.

Correct result:

F =  14 kN


S=7 dm2 m2=7/100  m2=0.07 m2 h=20 m g=10 m/s2 ρ=1000 kg/m3  F1=S h g ρ=0.07 20 10 1000=14000 N  F=F1/1000=14000/1000=14 kN
