1. What is Water Thermal Conductivity?

Thermal conductivity (k) is a measure of water's ability to conduct heat. It varies with temperature and is an important property in heat transfer calculations.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( k \) — Thermal conductivity (W/m·K)
• \( T \) — Temperature in Kelvin (K)

Explanation: This equation provides an approximate value for water's thermal conductivity based on temperature.

3. Importance of Thermal Conductivity

Details: Thermal conductivity is crucial for designing heat exchange systems, understanding natural convection processes, and modeling thermal properties in various engineering applications.

4. Using the Calculator

Tips: Enter temperature in Kelvin (K). The value must be valid (temperature > 0).

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this equation?
A: This is an approximate equation. For precise calculations, refer to detailed water property tables.

Q2: What are typical values for water's thermal conductivity?
A: At room temperature (298K), k ≈ 0.6 W/m·K. It increases with temperature.

Q3: Does this apply to ice or steam?
A: No, this equation is for liquid water only. Ice and steam have different thermal conductivity properties.

Q4: How does pressure affect thermal conductivity?
A: This equation doesn't account for pressure effects, which are generally small for liquid water.

Q5: What's the temperature range for this equation?
A: This approximation works best for temperatures between 273K and 373K (0°C to 100°C).
