Answer:
pecific volume of a unit can be expressed as
v = 1 / ρ = V / m (1)
where
v = specific volume (m3/kg, ft3/lb)
ρ = density (kg/m3, lb/ft3)
V = volume of unit (m3, ft3)
m = mass of unit (kg, lb)
The change in the units volume when temperature changes can be expressed as
dV = V0 β (t1 - t0) (2)
where
dV = V1 - V0 = change in volume (m3, ft3)
β = volumetric temperature expansion coefficient (m3/m3 oC, ft3/ft3 oF)
t1 = final temperature (oC, oF)
t0 = initial temperature (oC, oF)
The density of a fluid when temperature changes can be expressed as
ρ1 = m / V0 (1 + β (t1 - t0))
= ρ0 / (1 + β (t1 - t0)) (3)
where
ρ1 = final density (kg/m3, lb/ft3)
ρ0 = initial density (kg/m3, lb/ft3)
