Hydrostatic force

What hydrostatic force is applied to an area of 30 cm2 in water at a depth of 20 m? (Water density is 1000 kg/m3)

Correct result:

F =  588.6 N

Solution:

S=30 cm2 m2=30/10000  m2=0.003 m2 m2 h=20 m V=S h=0.003 20=350=0.06 m3 ρ=1000 kg/m3  m=ρ V=1000 0.06=60 kg g=9.81 m/s2 F=m g=60 9.81=29435=588 35=29435 N=588.6 N



We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
