The web tool calculates average temperature rise of each source over the ambient temperature of the fluid at the convectively-cooled lower surface of the substrate. The average source temperature rise is displayed in degrees Celsius on the heat source and, in the case of multiple sources, colours are used to indicate relative magnitude as shown below:
