What is specific volume formula?

Formula for Specific Volume

Specific volume is defined as the number of cubic meters occupied by one kilogram of matter. In other words, specific volume is inversely proportional to density. Specific volume may be calculated or measured for any state of matter, but it is most often used in calculations involving gases.

Also Know, how do you find the specific volume of a refrigerant? Specific volume for an ideal gas is also equal to the gas constant (R) multiplied by the temperature and then divided by the pressure multiplied by molar mass of that ideal gas.

In this way, 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 and water vapor (SI-units). The specific volume can be expressed as: v = V / ma + mw (11)

What is the symbol for specific volume?

Specific Volume. It is defined as the property of a material in which the substance of one kilogram contains the number of cubic meters. The unit of specific volume is m 3 / kg and it is represented by the symbol v.

What is PV nRT called?

PV = nRT: The Ideal Gas Law. Fifteen Examples Each unit occurs three times and the cube root yields L-atm / mol-K, the correct units for R when used in a gas law context. Consequently, we have: PV / nT = R. or, more commonly: PV = nRT. R is called the gas constant.

What is the value of R?

The value of the gas constant ‘R’ depends on the units used for pressure, volume and temperature. R = 0.0821 liter·atm/mol·K. R = 8.3145 J/mol·K. R = 8.2057 m3·atm/mol·K. R = 62.3637 L·Torr/mol·K or L·mmHg/mol·K.

How do I find the volume?

Units of Measure Volume = length x width x height. You only need to know one side to figure out the volume of a cube. The units of measure for volume are cubic units. Volume is in three-dimensions. You can multiply the sides in any order. Which side you call length, width, or height doesn’t matter.

How does specific gravity work?

Specific gravity. Apparent specific gravity is the ratio of the weight of a volume of the substance to the weight of an equal volume of the reference substance. The reference substance for liquids is nearly always water at its densest (at 4 °C or 39.2 °F); for gases it is air at room temperature (20 °C or 68 °F).

What is relative specific volume?

The specific volume is the reciprocal of the density. The relative specific volume i this relative to some starting condition or reference state. Relative pressure and relative specific volume are used to deal with the effect of changes on a system. The specific volume is the reciprocal of the density.

What is the difference between density and specific volume?

The specific volume of a substance is defined as the volume per unit mass. Typically specific volume uses the symbol v. 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 defined as mass per unit volume.

Is specific volume an intensive property?

Since the mass and volume are directly related to each other under static conditions, we can define a new property called the specific volume which is equal to the volume divided by the mass. Specific volume is an intensive property of the gas, as shown in our example.

How do you calculate specific gravity?

The Formula for Specific Gravity The density is directly related to the mass of the object (unit: usually in grams but can be measured in kilograms or pounds), so the specific gravity can also be determined by dividing the mass of the object by the mass of the water.

Whats is volume?

Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Displacement of liquid can also be used to determine the volume of a gas.

Is density a weight?

Weight density is weight of a substance per unit volume. Our definitions of mass and weight are made in such a way that weight in Kg is same as mass in Kg on earth surface in standard reference place. So an object will have same mass on earth and moon, but weight will be different at these two places.
