The specific volume is the reciprocal of the density of the material, which is the mass per unit volume: r = (1/v) = (m/V).
What is meant by specific volume?
Definition of specific volume
: the volume per unit mass of a substance : the reciprocal of the density.
What is specific volume in chemistry?
Specific volume is a property of materials, defined as the number of cubic meters occupied by one kilogram of a particular substance. The standard unit is the meter cubed per kilogram (m 3 /kg or m 3 · kg -1 ).
What is specific volume of gas?
The standard unit of specific volume is cubic meters per kilogram (m3/kg), but other units include ft3/lb, ft3/slug, or mL/g. Specific volume for an ideal gas is related to the molar gas constant (R) and the gas’s temperature (T), pressure (P), and molar mass (M) as shown: Since and.
What is the reciprocal of specific volume?
The density of a substance is defined as the mass per unit volume, and it is therefore the reciprocal of the specific volume. Density is designated by the symbol ρ.
How do you find a specific volume in a psychrometric chart?
From the psychrometric chart we can find out the specific volume of the required air and find the total volume of the required air by multiplying it with the total weight of the air required. The constant specific lines start from the saturation curve and drop down with the slight angle to the vertical lines.
How do you calculate specific gravity?
Calculating Specific Gravity
Specific gravity is determined by dividing the density of a material by the density of water at 4 degrees Celsius. For the calculation, the density of the material and that of the water must be expressed in the same units.
How do you 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.
How do you find total volume in chemistry?
Calculate the volume of the substance by dividing the mass of the substance by the density (volume = mass/density).
What is Voidage and how is it calculated?
The term voidage is normally used to refer to the tiny spaces between particles in a powder or granulated material like sand. The actual calculation of voidage is simple: it is the amount of empty space divided by the total volume.
What kind of property is specific volume?
Specific volume is an intensive property of the gas, as shown in our example. The specific volume of the original tank is the same as the specific volume in each half. The “specific” of specific volume simply means “divided by mass”.
What is the specific volume of air?
Specific volume of air in psychrometric chart is defined as the number of cubic meters occupied by one kilogram of a dry air.
How do you find the specific volume of a saturated liquid?
From the appropriate saturation table, at the given value of pressure or temperature we can find the values of vf and vg then use equation [5], v = vf + x(vg – vf), to find the specific volume.
Is specific volume extensive?
Temperature, pressure, and specific volume of both systems are intensive properties. Total mass and total volume of each system are extensive property. At 100oC and 1 atm, the specific volume v of each system is 1.674 m3/kg.
