A cylindrical can 150 mm in diameter is filled to a depth of 100 mm with a fuel oil. The oil has a mass of 1.56 kg. Calculate its density, specific weight and specific gravity.

Solution

Volume of the cylinder

V=pi*r²*h =pi*(150*10^-3)²*(100*10^-3)

V=7.07*10^-3 m³

a)

Density

p=m/V =1.56/(7.07*10^-3)

p=220.7 Kg/m³

b)

Specific weight

SW = pg =220.7*9.81

SW=2165 N/m³ or 2.165 KN/m³

c)

Specific gravity

SG =p_object/p_water =220.7/1000

SG=0.2207
