							Specific volume of a unit can be expressed as

v = 1 / ρ = V / m (1)

where

v = specific volume (m3/kg)

ρ = density (kg/m3)

V = volume of unit (m3)

m = mass of unit (kg)

The change in the units volume when temperature change can be expressed as

dV = V0β (t1- t0) (2)

where

dV = V1- V0= change in volume (m3)

β = volumetric temperature expansion coefficient (m3/m3 oC)

t1= final temperature (oC)

t0= initial temperature (oC)

The density of a fluid when the temperature is changed can be expressed as

ρ1= m / V0(1 + β (t1- t0))

= ρ0/ (1 + β (t1- t0)) (3)

where

ρ1= final density (kg/m3)

ρ0= initial density (kg/m3)501-727_Capture.PNG
