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.
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
