Alarge aquarium of height 6 m is filled with fresh water to a depth of d = 1.50 m. one wall of the aquarium consists of thick plastic with horizontal length w = 8.40 m. by how much does the total force on that wall increase if the aquarium is next filled to a depth of d = 4.30 m? (note: use g = 9.81 m/s2 and rho = 998 kg/m3.)

Answer

given,

height of aquarium = 6 m

Depth of fresh water = D = 1.50 m

horizontal length of the aquarium(w) = 8.40 m

total force increased when liquid is filled to depth = 4.30 m

g = 9.81 m/s²

ρ = 998 Kg/m³

force in the aquarium.

dF = PdA

At D = 1.5 m

F = 9.08 x 10⁴ N

At D = 4.30 m

F = 7.46 x 10⁵ N

Total force on the wall increased by

ΔF  = 74.6 x 10⁴ - 9.08 x 10⁴

ΔF  = 65.52 x 10⁴ N

amplitude

hope this
