1. What is Wet Bulb Relative Humidity?

Relative humidity (RH) is a measure of the amount of moisture in the air compared to the maximum amount the air can hold at a specific temperature. The wet bulb temperature is the lowest temperature that can be reached by evaporating water into the air.

2. How Does the Calculator Work?

The calculator uses the simplified formula:

Where:

• \( Dry \) — Dry bulb temperature (°C)
• \( Wet \) — Wet bulb temperature (°C)

Explanation: This formula provides an approximate calculation of relative humidity based on the difference between dry and wet bulb temperatures.

3. Importance of RH Calculation

Details: Relative humidity measurement is important for weather forecasting, HVAC systems, agricultural planning, industrial processes, and human comfort assessment.

4. Using the Calculator

Tips: Enter both dry and wet bulb temperatures in Celsius. The wet bulb temperature should be equal to or lower than the dry bulb temperature.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation method?
A: This formula provides an approximate calculation. For more precise results, psychrometric charts or more complex equations should be used.

Q2: What is the typical range for relative humidity?
A: Relative humidity ranges from 0% (completely dry air) to 100% (air saturated with moisture, like in fog or rain).

Q3: Why is wet bulb temperature important?
A: Wet bulb temperature helps determine the cooling effect of evaporation and is critical for heat stress assessment and cooling system design.

Q4: When is this approximation most accurate?
A: This formula works best in moderate temperature ranges and may be less accurate at extreme temperatures or humidity levels.

Q5: Can I use this for Fahrenheit temperatures?
A: No, this formula is designed for Celsius measurements. For Fahrenheit, you would need to convert temperatures first or use a different formula.
