Question

Water with a density of 62.3 lb/ft3 completely fills an 80-ft3 vessel. If the local acceleration of gravity is 32.08 ft/s2, determine the weight of the water, in lbf.

Answer 1

4969.44 lbf

Step-by-step explanation:

given,

Density of the water = 62.3 lb/ft³

volume of the vessel = 80 ft³

acceleration of gravity = 32.08 ft/s²

weight of the water = ?

we know,

mass = density x volume

m = 62.3 x 80

m = 4984 lb

weight of the water

W = m g

W = 4984 x 32.08

W = 159886.72 lbm. ft/s²

1 lbf = 32.174 lbm. ft/s²

`W = (159886.72)/(32.174)`

W = 4969.44 lbf

the weight of the water = 4969.44 lbf
