How do you find volume with specific pressure and temperature?
Specific Volume Formulas ν = 1 /ρ = ρ-1 where ρ is density. ν = RT / PM = RT / P where R is the ideal gas constant, T is temperature, P is pressure, and M is the molarity.
How do you calculate specific volume in thermodynamics?
To calculate specific volume you need to know the volume (V) and the mass (m). Specific volume equals volume divided by mass. Typically, volume is measured in cubic meters (m3), and mass is measured in kilograms. Specific volume is then calculated as volume divided by mass.
How do you find volume with moles pressure and temperature?
First, let’s review the ideal gas law, PV = nRT. In this equation, ‘P’ is the pressure in atmospheres, ‘V’ is the volume in liters, ‘n’ is the number of particles in moles, ‘T’ is the temperature in Kelvin and ‘R’ is the ideal gas constant (0.0821 liter atmospheres per moles Kelvin).
How do you calculate VF and VG?
For a liquid vapor mixture at equilibrium,
- V = Vf + Vg.
- (m3)
- And.
- m*v = mf*vf + mg* vf. (m3)
- (1)
- where m = total mass in both phases and V = total volume occupied by both. phases.
What is VG and VF?
vf = specific volume of saturated liquid, vg. = specific volume of saturated vapor, and. vfg = specific volume change upon vaporization.
How do you convert specific gravity to specific volume?
The “Specific Gravity” of a substance is the ratio of its mass to that of an equal volume of water at the same temperature and pressure. This is also the ratio of the densities of the two substances: SG = (mass of a volume V of a material)/(mass of a volume V of water) = (rMaterial/rWater).
