Centrifugal pumps - centrifugal principle

    Centrifugal inertia is the performance of an object, such as drops of water on the umbrella, when the umbrella slowly rotates, water droplets will follow the umbrella rotation, this is because the friction of water droplets as the umbrella and the centripetal force to the droplet dictates. However, if the rotation speed up the umbrella, the friction enough to make water droplets in a circular motion, then drop the sport from the umbrella to the outer edge, like a rope pulling the stones in a circular motion, if the speed is too fast, the rope will disconnect, stones will be flying out. This is the so-called centrifugal.
