How to use this tool
- Enter heat transfer coefficient, area, surface temperature, bulk fluid temperature.
- Select Calculate to view the result.
- Check the method and assumptions below before using the result.
The method, explained
Heat rate = hA(Tsurface−Tfluid).
Using heat transfer coefficient = 10 W/(m²·K), area = 2 m², surface temperature = 80 °C, bulk fluid temperature = 20 °C, the result is 1200 W. Change these example inputs to match your task; use the method above to check each step.
Understanding your result
The coefficient must suit the geometry and flow. The tool does not infer h from air speed or fluid properties.
What to keep in mind
The coefficient must suit the geometry and flow. The tool does not infer h from air speed or fluid properties. An idealized educational model using the stated SI units. Real systems may need additional forces, losses or experimental measurements. Not a safety or equipment specification.
Common questions
How do I use this convection heat transfer calculator?
Estimate heat transfer using a specified convective heat-transfer coefficient. Enter heat transfer coefficient in W/(m²·K), area in m², surface temperature in °C, bulk fluid temperature in °C. The starting example is editable; use values for the same system or project.
Which assumptions affect this result?
