Critical Speed: Meaning, Examples & Analysis StudySmarter
So, our equation of motion is: F c = m a c, F N + m g = m v 2 r. To find the critical speed, we set the normal force to zero, as we did with the tension before, and we arrive at the same equation for the critical speed: 0 + m g = m v c 2 r, v c = g r. So the critical speed of the passenger is v c = 9.81 m s 2 ⋅ 15 m = 12 m s.calculating critical speed in a ball mill Indofact,Critical speed of ball mill derivation The formula to calculate critical speed is given below n c 42305 sqtdd n c critical speed of the mill d mill diameter specified in meters d diameter of the ball in practice ball mills are driven at a speed of 5090 of the critical speed the factor being influenced by economic consideration get price.
