Heat Transfer by Convection calculator

Heat transfer by convection refers to the transfer of heat between a solid surface and a fluid (liquid or gas) in motion. The rate of heat transfer by convection can be calculated using Newton’s Law of Cooling/Heating, which states:

Where:

• $Q$ is the heat transfer rate (in watts, W)
• $h$ is the convective heat transfer coefficient (in watts per square meter per Kelvin, W/(m²·K))
• $A$ is the surface area through which heat is being transferred (in square meters, m²)
• $\Delta T$ is the temperature difference between the surface and the fluid (in Kelvin, K)
