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 the specific volume of a mixture?
The specific volume in the mixed region is V/m, which can be found by dividing equation [1] by the total mass, m . We define the quality, x, as the mass fraction of vapor in the mixed region.
What is the specific volume of liquid water?
The specific volume that correlates to that density is 0.00094 m 3 /kg. Notice that the average specific volume of blood is almost identical to that of water: 0.00100 m 3 /kg .
What is meant by specific volume?
: the volume per unit mass of a substance : the reciprocal of the density.
How do you find the specific volume of water?
- ν = V / m where V is volume and m is mass.
- 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.
What is specific volume of steam?
SPECIFIC VOLUME OF STEAM The specific volume is the volume occupied by the unit mass of a substance . It is expressed in m3/kg . The volume of water and steam increase with the increase in temperature.
What is specific air volume?
Specific volume is defined as the total volume of dry air and water vapor mixture per kg of dry air (SI-units).
What is the formula of volume?
| Table 3. Volume Formulas | Shape Formula Variables | Cube V=s3 s is the length of the side. | Right Rectangular Prism V=LWH L is the length, W is the width and H is the height. | Prism or Cylinder V=Ah A is the area of the base, h is the height. |

What is the symbol for specific volume?
Specific volume, abbreviated as υ (Greek symbol upsilon), is the volume in a unit of mass. Specific volume is a intensive variable whose physical quantity value does not depend on the amount of the substance for which it is measured.
How do you find volume in PV nRT?
- P=nRTV. Calculate volume:
- V=nRTP. Calculate moles:
- n=PVRT. Calculate temperature:
- T=PVnR.
What is meant by control volume?
Control volume is a volume in space of special interest for particular analysis . The surface of the control volume is referred as a control surface and is a closed surface. The surface is defined with relative to a coordinate system that may be fixed, moving or rotating.
What is the dimension of Specific volume?
It is defined as the volume per unit mass. Thus, L 3 M – 1 T 0 is the dimensional formula of Specific volume.
How do you find final Specific volume?
Solution: First, the mass of the gas in each compartment is calculated with m=V/v using the initial state. During the prcoess, the mass is constant for each compartment but the volume changes. Thus, the final specific volumes are calculated using the final volumes and original masses with v=V/m.
What is difference between volume and specific volume?
Volume is a thermodynamic property of a substance. Specific volume is the volume of a unit mass of a substance. The difference between volume and specific volume is that volume is an extensive property whereas specific volume is an intensive property.
What is the volume of 1g of steam?
The volume of steam produced by 1g of water at 100°c is 1650 cm3 .
How do I calculate specific weight?
Multiply the density by the acceleration of gravity (9.81) to calculate the specific weight. In our example, the specific weight is 840 x 9.81 = 8,240.4.
