What does the Big B in the volume formula represent?
The volume formula for a cylinder is V = Bh where B represents the area of the base of the shape and h is the height of the prism or cylinder. This formula is used to find the volume of a geometric prism or cylinder.
What is the mathematical expression of volume?
Volume Formula: Volume = l × w × h , where l is length, w is width and h is height. Volume = 4/3 πr³ , where r is the radius.
What is the use of 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.
What is the symbol of 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.
What is the difference between density and specific volume?
The specific volume of a substance is defined as the volume per unit mass. 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.
What is the meaning 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). Specific volume is inversely proportional to density.
What is unit of humid volume?
Absolute humidity describes the water content of air and is expressed in either grams per cubic metre or grams per kilogram. Relative humidity, expressed as a percentage, indicates a present state of absolute humidity relative to a maximum humidity given the same temperature.
How humidity is calculated?
Just like water vapor, relative humidity can be expressed in terms of pressure or density. In both cases it is expressed as a percentage and is calculated by dividing actual vapor pressure by saturation vapor pressure (or actual vapor density by saturation vapor density), then multiplying that number by 100.
How do you find the specific volume of a gas?
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 , v = vf + x(vg – vf), to find the specific volume.
How do you convert volume to density?
The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.
