1. What is Wet Bulb Temperature?

Definition: Wet bulb temperature is the lowest temperature to which air can be cooled by evaporating water into it at constant pressure.

Purpose: It's important in meteorology, HVAC design, and industrial processes where humidity control is critical.

2. How Does the Calculator Work?

The calculator uses the approximate formula:

Where:

• \( Wet \) — Wet bulb temperature (°C)
• \( Dry \) — Dry bulb temperature (°C)
• \( RH \) — Relative humidity (%)

Explanation: This simplified formula provides a quick estimation of wet bulb temperature from dry bulb temperature and relative humidity.

3. Importance of Wet Bulb Temperature

Details: Wet bulb temperature is crucial for understanding human comfort, predicting frost formation, and designing cooling systems.

4. Using the Calculator

Tips: Enter the dry bulb temperature in °C and relative humidity in % (must be between 0-100). The calculator will estimate the wet bulb temperature.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this formula?
A: This is an approximation. For precise calculations, more complex psychrometric formulas are needed.

Q2: What's the range of validity for this formula?
A: It works reasonably well for temperatures between 0-50°C and RH between 20-100%.

Q3: Why is wet bulb temperature important for human health?
A: It indicates how effectively humans can cool themselves through sweating. Values above 35°C can be dangerous.

Q4: How does this relate to the heat index?
A: Both measure perceived temperature, but heat index considers more factors for human comfort.

Q5: When would I need exact wet bulb calculations?
A: For precise HVAC design, industrial drying processes, or scientific research, use psychrometric charts or more detailed formulas.
