What is meaning of specific volume?
: the volume per unit mass of a substance : the reciprocal of the density.
What is the specific volume in fluid mechanics?
The specific volume of a fluid is the volume occupied by unit mass of fluid. For liquids, it is the ratio of density of a liquid at actual conditions to the density of pure water at 101 kN/m2 , and at 4°C.
Is there a difference between total and specific volume?
Volume is a thermodynamic property of a substance. Specific volume is the volume of a unit mass of a substance. The difference between volume and specific volume is that volume is an extensive property whereas specific volume is an intensive property.
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.
Is specific volume intensive or extensive?
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 difference between specific weight and specific volume?
The specific volume of a substance is the proportion of the substance’s volume to its mass. The particular weight (otherwise called the unit weight) is the weight per unit volume of a material. …
Why do we use specific volume?
Specific volume is most often used in engineering and in thermodynamics calculations for physics and chemistry. It is used to make predictions about the behavior of gases when conditions change.
Is specific volume dependent on pressure?
The value of pressure and temperature does not depend on the amount of gas used in the measurement. The mass of the gas, on the other hand, does depend on the volume. Cutting the volume in two cuts the mass in two. Specific volume is an intensive property of the gas, as shown in our example.
Is volume physical or chemical?
Mass and volume are both examples of extensive physical properties.
What is unit 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).
What is Gamma in fluid mechanics?
Specific weight, sometimes referred to as unit weight, is simply the weight of fluid per unit volume. It is usually denoted by the Greek letter γ (gamma) and has dimensions of force per unit volume.
What is specificspecific volume?
Specific volume is defined as the number of cubic meters occupied by one kilogram of matter. It is the ratio of a material’s volume to its mass, which is the same as the reciprocal of its density.
What is the engine volume of a car?
The Engine Volume is also measured in Liters corresponding to Cubic Centimeters. If an engine has a capacity of say 1000cc or 1000 Cubic Centimeters, then the capacity of that engine is 1 Liter.
How do you calculate specific volume from 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.
What is the standard unit for specific volume?
The standard unit for specific volume is cubic meters per kilogram (m 3 /kg), although it may be expressed in terms of milliliters per gram (mL/g) or cubic feet per pound (ft 3 /lb). The “specific” part of a specific volume means that it is expressed in terms of unit mass.
