where k is the specific wear rate for abrasion of the rubber by the iron ore, V is the speed of the belt, μ is the coefficient of friction between the bed of ore and the belt surface, w is the width of the belt, and L is the overall (end-to-end) length of the conveyor. Make your assumptions clear. (b) In one particular conveyor, 1100 m long, 1.8 wide, and moving at …
