Heat Transfer Coefficient Converter

Heat Transfer Coefficient Unit Converter

Description:

A heat transfer coefficient unit converter is a tool used to convert between different units of heat transfer coefficient, which measures the rate of heat transfer through a material per unit area per unit temperature difference. Heat transfer coefficient is a crucial parameter in fields such as thermodynamics, engineering, and building construction, where understanding heat flow is essential.

Units:

1. Watt/square meter/K
2. Watt/square meter/°C
3. Joule/second/square meter/K
4. Calorie (IT)/second/square centimeter/°C
5. Kilocalorie (IT)/hour/square meter/°C
6. Kilocalorie (IT)/hour/square foot/°C
7. Btu (IT)/second/square foot/°F
8. Btu (th)/second/square foot/°F
9. Btu (IT)/hour/square foot/°F
10. Btu (th)/hour/square foot/°F
11. CHU/hour/square foot/°C

Formula:

The heat transfer coefficient (h) can be calculated using the formula:

$h = \frac{Q}{A \cdot \Delta T}$

Where:

• $h$ = Heat transfer coefficient (in the desired unit)
• $Q$ = Heat transfer rate (in watts, joules/second, or its equivalent)
• $A$ = Surface area through which heat is transferred (in square meters or its equivalent)
• $\Delta T$ = Temperature difference across the material (in kelvin, degrees Celsius, or degrees Fahrenheit)

How to Convert:

To convert between different units of heat transfer coefficient, follow these steps:

1. Identify the unit you have and the unit you want to convert to.
2. Determine the conversion factor between the two units. This factor may involve simple multiplication or division.
3. Multiply or divide the heat transfer coefficient value by the conversion factor to obtain the equivalent value in the desired unit.

Examples:

1. Conversion from Watt/square meter/K to Btu (IT)/second/square foot/°F:Conversion Factor: 1 watt = 3.41214 Btu/hour, 1 square meter = 10.7639 square feet, 1 kelvin = 1.8 degrees Fahrenheit$1 \, \text{W/m}^2/\text{K} = \frac{3.41214}{10.7639 \times 1.8} \, \text{Btu (IT)/s/ft}^2/°F$

2. Conversion from Joule/second/square meter/K to Kilocalorie (IT)/hour/square foot/°C:Conversion Factor: 1 joule = 0.000239006 kilocalorie, 1 square meter = 10.7639 square feet, 1 kelvin = 1 degree Celsius$1 \, \text{J/s/m}^2/\text{K} = \frac{0.000239006 \times 3600}{10.7639} \, \text{kcal (IT)/h/ft}^2/°C$

3. Conversion from Calorie (IT)/second/square centimeter/°C to CHU/hour/square foot/°C:Conversion Factor: 1 calorie (IT) = 4.184 joules, 1 square centimeter = 0.00107639 square feet, 1 hour = 3600 seconds$1 \, \text{cal (IT)/s/cm}^2/°C = \frac{4.184 \times 3600}{0.00107639} \, \text{CHU/h/ft}^2/°C$

By following these steps, you can accurately convert between various units of heat transfer coefficient, enabling efficient analysis and communication in heat transfer-related applications.
