Description
Comprises a tin plate cube with 130mm sides.
Each of the four vertical sides of the cube has a different surface –
1x blackened, 1x roughened, 1x polished and 1x varnished. An opening at the top of the cube enables it to be filled with water almost to the top and then heated to boiling point over a bunsen burner flame.
The relative radiant heat output from each of the four faces of the cube can then be measured by using a thermometer or with infra red sensors –
