How to calculate speed: blade tips and more

Sep 23, 2013· To find tip speed, we need the rotor diameter and rotational rate So assume a rotor diameter of 100m and a rotation rate (ω) of 15 revolutions/min, rpm Distance in this case is the circumference C of the rotor’s circle, which is found with: C = πD Where D = diameter in meters, m So our 100m rotor describes a circumference of: C = π x 100m
