Translator In unloading a grain from a hold of a ship, an elevator lifts the grain through a distance of 12 m. Grain is discharged at the top of the elevator at a rate of 2.0 kg each second, and the discharged speed of each grain particle is 3 m/s Find the minimum-horsepower motor that can elevate the grain in this way if it is 60% efficient.
