1. What is Saturated Steam Temperature?

Saturated steam temperature is the temperature at which water vapor and liquid water coexist in equilibrium at a given pressure. It represents the boiling point of water at that specific pressure condition.

2. How Does the Calculator Work?

The calculator uses steam tables or Antoine equation to determine saturated temperature:

Where:

• \( T_{sat} \) — Saturated temperature (°C)
• \( P \) — Pressure (Pa)

Explanation: The relationship between pressure and saturated temperature is non-linear and is precisely defined in steam tables or can be calculated using the Antoine equation for water.

3. Importance of Saturated Temperature Calculation

Details: Accurate saturated temperature calculation is crucial for power plant operations, heat exchanger design, process engineering, and various industrial applications involving steam systems.

4. Using the Calculator

Tips: Enter pressure in Pascals (Pa). The calculator will return the corresponding saturated steam temperature in degrees Celsius (°C).

5. Frequently Asked Questions (FAQ)

Q1: What are steam tables?
A: Steam tables are comprehensive data tables that provide thermodynamic properties of water and steam, including the relationship between pressure and saturated temperature.

Q2: What is the Antoine equation?
A: The Antoine equation is a mathematical expression that describes the relationship between vapor pressure and temperature for pure substances, including water.

Q3: Why does boiling point increase with pressure?
A: Higher pressure requires more energy for water molecules to escape the liquid phase, resulting in a higher boiling point temperature.

Q4: What is the saturation temperature at atmospheric pressure?
A: At standard atmospheric pressure (101325 Pa), the saturation temperature of water is 100°C.

Q5: Are there limitations to steam table calculations?
A: Steam tables provide accurate data for pure water. For water with impurities or in extreme conditions, additional corrections may be necessary.
