## What is meant by 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·kg1).

## 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) where. v = specific volume of moist air per mass unit of dry air and water vapor (m3/kg)

## How do you find the specific volume of water?

The specific volume (ν) of a substance is the total volume (V) of that substance divided by the total mass (m) of that substance (volume per unit mass). It has units of cubic meter per kilogram (m3/kg).

## How do you find specific gravity from specific volume?

We start by finding the density of the object. Remember, finding the density involves dividing the mass by the volume. If the mass is 36 grams and the volume is 3 mililiters, then the density of the object is 12 grams per milliliter. That means that the specific gravity will be 12.

## Why do we use specific volume?

Uses of Specific Volume It is used to make predictions about the behavior of gases when conditions change. Consider an airtight chamber containing a set number of molecules: If the chamber expands while the number of molecules remains constant, the gas density decreases and the specific volume increases.

## 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. Vsup = Specific volume of superheated steam at pressure P.

## What is specific mass?

a. The quantity of something per unit measure, especially per unit length, area, or volume. b. The mass per unit volume of a substance under specified conditions of pressure and temperature.

## How do you find pressure from volume?

The law is given by the following equation: PV = nRT, where P = pressure, V = volume, n = number of moles, R is the universal gas constant, which equals 0.0821 L-atm / mole-K, and T is the temperature in Kelvin.

## How do I find the volume?

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.

## What is the critical specific volume of water?

The specific volume of water at the critical point is 0.003155 m3/kg.

## 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. Measure or obtain elsewhere the volume of the substance.

## What is the symbol of specific weight?

The terms specific gravity, and less often specific weight, are also used for relative density. A common symbol for specific weight is γ, the Greek letter Gamma.

## How do you test specific gravity?

The normal method of determining specific gravity is to weigh the specimen dry (DW), then to suspend the specimen in water on a string, and to measure the weight pulling on the string (WW) (specimen weight suspended in water). Then you subtract WW from DW, and divide the difference into DW.

#### Equation of vertical line

How do you write an equation for a vertical and horizontal line? Horizontal lines go left and right and are in the form of y = b where b represents the y intercept. Vertical lines go up and down and are in the form of x = a where a represents the shared x coordinate […]

#### Bernoulli’s equation example

What does Bernoulli’s equation State? Bernoulli’s principle states the following, Bernoulli’s principle: Within a horizontal flow of fluid, points of higher fluid speed will have less pressure than points of slower fluid speed. Why is Bernoulli’s equation used? The Bernoulli equation is an important expression relating pressure, height and velocity of a fluid at one […]
