between the maximum and minimum . equilibrium speed to mean equilibrium
Practically, from no load to full load operation of the engine, a definite
2 ) Proell Governor :-
Radius of rotation at speed N1,
r1 = 0.05 + s1 + d1mtr.
Now, finding C1 similar to Porter governor, at speed N1.
Applying pythagores theorem
Ѳ = tan-1 (C1 / S1 )
As total included angle of link EFH is 1500
Ѳ1 + α + 90 = 150
α1 = (60 – P1)2
d1 = a sin α1.
= 0.07 sin α1
∴ r1 = (0.05 + S1 + d1).
Similar to Porter governor
