how to find specific volume

How To Find Specific Volume?

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.Aug 20, 2017

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 value of specific volume?

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 (m³/kg or m³·kg⁻¹).

Is specific volume the same as density?

The specific volume is the reciprocal of the density of the material, which is the mass per unit volume: r = (1/v) = (m/V). 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.

What is specific volume of water?

A common unit of measurement for water’s density is gram per milliliter (1 g/ml) or 1 gram per cubic centimeter (1 g/cm³). Actually, the exact density of water is not really 1 g/ml, but rather a bit less (very, very little less), at 0.9998395 g/ml at 4.0° Celsius (39.2° Fahrenheit).

How do you find a specific volume on 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 measure the volume of a drum?

Multiply the radius squared times pi times the height of the drum. Pi is approximately 3.14159265. The final result is the volume of the drum in cubic units, the same units you used to make the measurements. For example, calculate the radius squared (81 inches) times pi, then times the height (36 inches).

How do you do volume in math?

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.

What unit is volume?

cubic meter

Volume is the measure of the 3-dimensional space occupied by matter, or enclosed by a surface, measured in cubic units. The SI unit of volume is the cubic meter (m³), which is a derived unit.

How do you convert density to specific volume?

Density is defined as mass per unit volume. The reciprocal of density is the specific volume v, which is defined as volume per unit mass. That is, v = V/m = 1/ρ. For a differential volume element of mass δm and volume δV, density can be expressed as ρ = δm/δV.

How do you find volume with only density?

The formula for density is the mass of an object divided by its volume. In equation form, that’s d = m/v , where d is the density, m is the mass and v is the volume of the object.

Is specific volume a state function?

The specific volume of a substance can be defined as the ratio of the substance’s volume to its mass. It does not depend on that path taken as it is measured for a state and not a route. So, it is a state function.

What is the specific volume of oxygen?

How do I find specific volume in steam?

Specific volume is defined as the number of cubic meters occupied by one kilogram of matter.
…
Specific Volume Formulas

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 the specific volume of water and ice?

Pure water has its highest density of 1000 kg/m³ at a temperature of 3.98^oC (39.2^oF). Water differs from most liquids in that it becomes less dense as it freezes. It has a maximum density of 3.98 °C (1000 kg/m³), whereas the density of ice is 917 kg/m³. It differs by about 9%, and therefore ice floats on liquid water.

How do you calculate specific volume of a wet steam?

Specific Volume (ν) of Wet Steam

X = Dryness (% / 100)

What is specific volume in psychrometric?

Specific volume of air in psychrometric chart is defined as the number of cubic meters occupied by one kilogram of a dry air. So units of specific volume is m³ kg^–¹.

What is specific volume in air conditioning?

Specific volume is defined as the total volume of dry air and water vapor mixture per kg of dry air (SI-units).

How do you convert specific weight to specific volume?

If the volume is given in liters, then divide it by 1,000. If it is measured in gallons, then multiply the value by 0.003785. For example, 5.2 liters will convert to 0.0052 (5.2 / 1,000) cubic meter. Multiply the specific weight of the substance by the volume to calculate the weight.

What is the volume of a solution?

Volume Percent: The volume percent is used to express the concentration of a solution when the volume of a solute and the volume of a solution is given: Volume Percent=Volume of SoluteVolume of Solution×100%

How do you find volume when given mass?

Divide the mass by the density of the substance to determine the volume (mass/density = volume).

What is PV equal to nRT?

PV=nRT. The ideal gas Law PV = nRT. Robert Boyle found PV = a constant. That is, the product of the pressure of a gas times the volume of a gas is a constant for a given sample of gas. In Boyle’s experiments the Temperature (T) did not change, nor did the number of moles (n) of gas present.

What is equivalent to PV nRT?

V = nRT / P. Moles (n) can be set equal to PV / RT: n = PV / RT. The ideal gas constant (R) can be set equal to PV / nT: R = PV / nT.

How do you solve for PV nRT?

How do you calculate the volume of a room?

Calculate the volume by multiplying the measured length and width of the space together, then multiply the result by the height of the room. From the example, 10 * 25 feet = 250 square feet, and 5 * 10 feet = 50 square feet.

How do you calculate the volume of a drum in Litres?

OR Litres

Cylinders have a volume in litres.
To calculate the volume of a cylinder, use the following equation V = πr²h.
The density of water is 1kg/litre so 1 litre = 1000cm^3.
To convert to millilitres divide by 1000 (1000ml=1 litre)

What is the volume of this container?

The basic formula for calculating the volume of a container is to multiply the length by the width by the depth. Assuming you measure all three dimensions in inches, the resulting figure will be in cubic inches.

What are 3 ways to measure volume?

What is the volume in mathematics?

In math, volume is the amount of space in a certain 3D object. For instance, a fish tank has 3 feet in length, 1 foot in width and two feet in height. To find the volume, you multiply length times width times height, which is 3x1x2, which equals six. So the volume of the fish tank is 6 cubic feet.
