EM MAN FUEL 20-
The scale on the left measures manifold (air) pressure in inches of mercury. (Mercury
can be represented by the symbol Hg.) The scale on the right measures fuel flow in
gallons per hour. Take some time to study the different scales used on the gauge, and
answer the following questions:
(a) What do you notice about the spacing of the consecutive tick marks for the
manifold pressure scale?
(b) What do you notice about the spacing of the consecutive tick marks for the
fuel flow scale?
(c) Based on your answers above, which of the two scales could be modeled by a
constant-rate relationship?
