What is the box ratio

Reference no: EM13536139

A mining lift, with a 80kg cage, should be able to pull up to the surface ten 90kg miners, from a 20m deep well, in 20s. If the gearboxes available have an efficiency of 75%, what should be the power rating of the DC motor used. If the driving gear pulling up the cable has a diameter of 20cm, and our motor full load speed is 900rpm, what is the box ratio, a.
