Fields

A field is a volume or area of space within which a condition exists.

For example, 10(field,heat) represents a volume within which the heat rating is 10. If its a spherical volume with a radius of 5 metres, we express it as:

5(radius) 10(field,heat)

If we want to say that the volume is shaped into a spray or a cone, then we use:

15(spray) 10(field,heat)
10(cone) 10(field,heat)
