1. What is the Saturated Vapor Pressure Equation?

The saturated vapor pressure equation calculates the maximum pressure of water vapor that can exist in equilibrium with its liquid phase at a given temperature. It's a fundamental concept in meteorology and thermodynamics.

2. How Does the Calculator Work?

The calculator uses the saturated vapor pressure equation:

Where:

• \( e_s \) — Saturated vapor pressure (hPa)
• \( T \) — Temperature (°C)
• \( \exp \) — Exponential function

Explanation: This empirical formula provides an accurate approximation of saturated vapor pressure over liquid water for temperatures between 0°C and 100°C.

3. Importance of Saturated Vapor Pressure Calculation

Details: Saturated vapor pressure is crucial for understanding humidity, predicting weather patterns, designing HVAC systems, and various industrial processes involving water vapor.

4. Using the Calculator

Tips: Enter temperature in degrees Celsius. The calculator will compute the saturated vapor pressure in hectopascals (hPa).

5. Frequently Asked Questions (FAQ)

Q1: What is the physical significance of saturated vapor pressure?
A: It represents the maximum amount of water vapor that air can hold at a specific temperature before condensation occurs.

Q2: How does temperature affect saturated vapor pressure?
A: Saturated vapor pressure increases exponentially with temperature - warmer air can hold significantly more water vapor.

Q3: What are typical values of saturated vapor pressure?
A: At 0°C: ~6.11 hPa, at 20°C: ~23.39 hPa, at 100°C: ~1013.25 hPa (atmospheric pressure at sea level).

Q4: Are there different formulas for different temperature ranges?
A: Yes, different empirical formulas exist for various temperature ranges and for vapor pressure over ice versus liquid water.

Q5: How is relative humidity related to saturated vapor pressure?
A: Relative humidity = (actual vapor pressure / saturated vapor pressure) × 100%. It indicates how close the air is to saturation.
