What is the formula for the slot pitch factor in design of rotors?
(a) slot pitch factor = 3.14*rotor diameter*number of rotor slots
(b) slot pitch factor = 3.14/rotor diameter*number of rotor slots
(c) slot pitch factor = 3.14*rotor diameter/number of rotor slots
(d) slot pitch factor = 1/3.14*rotor diameter*number of rotor slots
I have been asked this question in an internship interview.
