## How do you calculate specific volume of water?

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

1. ν = V / m where V is volume and m is mass.
2. ν = 1 /ρ = ρ-1 where ρ is density.
3. 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 critical specific volume of water?

0.003155 m3/kg.
Water has a critical specific volume of 0.003155 m3/kg.

#### What is the CP value of water?

4.186 J/g°C
Water has a specific heat capacity of 4.186 J/g°C, meaning that it requires 4.186 J of energy (1 calorie) to heat a gram by one degree.

What is R for water?

The value of the specific gas constant of water vapour is known to be equal to 0.4615 kilojoules per kilogram Kelvin or 461.5 joules per kilogram Kelvin.

What is specific gravity of water?

to 1
Water has a specific gravity equal to 1. Materials with a specific gravity less than 1 are less dense than water, and will float on the pure liquid; substances with a specific gravity more than 1 are more dense than water, and will sink.

## What is CP and CV of water?

In thermodynamics, there are two kinds of specific heats: Cv (specific heat at constant volume) and Cp (specific heat at constant pressure). Cv is the energy required to raise the temperature of a unit mass of a substance by one degree as the volume is held constant.

### What does CP and CV mean?

CV and CP are two terms used in thermodynamics. CV is the specific heat at constant volume, and CP is the specific heat at constant pressure.

#### What is water volume?

The mass of water is expressed in grams (g) or kilograms (kg), and the volume is measured in liters (L), cubic centimeters (cm3), or milliliters (mL). Density is calculated by the dividing the mass by the volume, so that density is measured as units of mass/volume, often g/mL.
