Default Unsteady Fan Simulation Time step

rvl565 is on a distinguished road

I have been running unsteady fan simulations in fluent using the sliding mesh technique.
I am not sure what time step i am supposed to use. Till now i have been using dt = the time take by the fan to rotate 1 degree.

How should i determine dt?

Also how should i determine how many iterations per time step to use?
