Steam flow rate = 500 kg/hr
If you do not need energy calculations, you can leave this value empty or enter zero.
Step 4: Enter Steam Quality
Enter steam quality as a percentage between:
0% and 100%
Steam quality describes how much of the steam mixture is vapor compared to liquid water.
Examples:
- 100% = Dry steam
- 50% = Half steam and half water mixture
- 0% = Liquid water

Understanding the Steam Properties Formula
The Steam Properties Calculator uses basic thermodynamic relationships to estimate steam characteristics.
1. Specific Volume Formula
Specific volume is calculated using the ideal gas relationship:
Specific Volume = (Gas Constant × Absolute Temperature) ÷ Pressure
Where:
- Gas constant for steam = approximately 0.4615 kJ/kg·K
- Temperature is converted from Celsius to Kelvin
- Pressure is converted into compatible units
The formula estimates how much volume one kilogram of steam occupies.
2. Density Formula
Density is the opposite of specific volume.
Formula:
Density = 1 ÷ Specific Volume
For example:
If specific volume is 1 m³/kg:
Density = 1 ÷ 1
Density = 1 kg/m³
3. Enthalpy Formula
Steam enthalpy is estimated using:
Enthalpy = Sensible Heat + Latent Heat Contribution
Where:
- Sensible heat represents heat added to raise temperature
- Latent heat represents energy required for water-to-steam conversion
- Steam quality determines the percentage of latent heat included
Approximate formula:
Enthalpy = (4.18 × Temperature) + (2257 × Steam Quality)
4. Energy Flow Formula
Energy flow rate is calculated using:
Energy Flow = (Steam Flow Rate × Enthalpy) ÷ 3600
Where:
- Steam flow rate is measured in kg/hr
- Enthalpy is measured in kJ/kg
- Result is converted into kW
Practical Example of Steam Properties Calculation
Suppose an industrial boiler produces steam with the following conditions:
- Pressure: 10 bar
- Temperature: 200°C
- Flow rate: 1,000 kg/hr
- Steam quality: 100%
Step 1: Enter Values
Pressure:
10 bar
Temperature:
200°C
Flow rate:
1,000 kg/hr
Quality:
100%
Step 2: Calculator Estimates Results

Specific Volume:
Around 0.218 m³/kg
Steam Density:
Around 4.59 kg/m³
Enthalpy:
Approximately 3093 kJ/kg
Energy Flow Rate:
Around 859 kW
Steam Condition:
