Application of The Principle of Flotation

A piece of me...

Question

A piece of metal weights 175kgwt in air and 150 kgwt when immersed in water.
Calculate the loss in weight, bioyant force and the volume of liquid displaced.

Open in App

Solution

1 kgwt = 9.8 newtons
loss in weight = (175-150)9.8 = 245 newton
Buoyant force = loss in weight = 245 newton
buoyant force = density volume of liquid displaced * g
volume of liquid displaced = 245 / (1000*9.8) = 0.025 m³ = 25 litre
