The speed of a belt is given by the formula ' V = Pi dn ', where V is the speed of the belt in metres per minute, d the diameter of the pulley in metres and n the number of revolutions per minute. A machine belt runs at 400 metres per minute over a pulley running at 200 rpm. What is the diameter of the pulley?
Thank you and may I please have this answered as soon as possible.
