The sensitiveness of the governor is defined as the ratio of the difference between the maximum and minimum equilibrium speed to the mean equilibrium speed.
Let, N‌1 = Minimum equilibrium speed,
N‌2 = Maximum equilibrium speed, and
N = Mean equilibrium speed =

(N1+N2)

2

Therefore,
Sensitiveness of the governor =

(N1−N2)

2

=

2(N2−N1)

(N1+N2)

=

2(ω2−ω1)

(ω1+ω2)
