Nomographs
Figure 10 Typical Nomograph
A nomograph is a device used to relate the
physical quantities in such a way that the value of
an unknown quantity can be determined given the
values of the other related quantities. Nomographs
normally involve the relationship among three
physical quantities. The scales are located in
such a way that, when a straight line is drawn
between the values of the known quantities on
their respective scales, the line crosses the value
of the unknown quantity on its scale. Figure 10
is a typical nomograph that relates the distance
traveled, the average speed, and the time traveled.
It should be noted that, as with any graphical
representation, the values determined are only
approximations.
