Question

An aquarium 5' long 2' wide and 3' deep is full of water. a) find the hydrostatic pressure on the bottom of the aquarium and force on the bottom

Answer 1

The pressure is 62.4 x depth = 62.4(3) = 187.2 pounds. The force on the bottom is equal to the weight of the water = 62.4(5)(2)(3) = 1872 pounds.

Answer 2

Pressure due to a column of height \(h\) of fluid of density \(\rho\):
\(P = \rho gh\)

Answer 3

by definition, \[P={F\over A}\implies F=PA=P(l\times w)\]

Answer 4

you'd first have to match the units for the lengths
