What is specific mass or mass density in Fluid Mechanics
This is the property of matter which is the ratio of matter occupied per unit volume.
specific mass or mass density = matter occupied /1 volume
The ratio of mass of the fluid (m) to its volume (V)
ρ = m/V
Unit is kg/m3
This is designated as ρ
ρair = 1.2 kg//m3
ρwater = 1000 kg//m3
ρHg = 13600kg//m3
ρgold = 19200 kg//m3
ρpt = 22500 kg//m3
