Seeking help with heat transfer coefficient
Thread Content
I would like to ask the experts here: As shown in the diagram, there is a container filled with liquid, and an electric heater is installed at the bottom of the container. Question: How should the heat transfer coefficient between the surface of the electric heater and the liquid in the tank be determined?
The heat transfer coefficient is determined by the material and the type of medium.
So it’s simply chosen based on experience? Has it been calculated by looking up the physical properties of the medium? For example, just like calculating the natural convection heat dissipation in a space, thank you
