A fan moves at 350 rpm. Find average speed of the tip in minutes if the blade length from the centre is 1m |

Answer» The angular velocity is w. Lets CALCULATE it : 350 REV per minute How many revolutions per second? 350 / 60 = 5.83 revolutions per second. One REVOLUTION = 2π Angular velocity = 2 π × 5.83 = 11.66π radians The linear velocity = RW Where r = radius, w=angular velocity V = 1 × 11.66π = 36.63 m/s |
