It is required that the drawworks input power be able to lift 600,000 Ib at a rate of 50 ft/min. There are eight working lines between the traveling block and the crown block. Three input power systems are available: 1,100, 1,400 and 1,800 hp. Considering that individual sheave efficiency is 96% and the draworks mechanical efficiency is 85%, which of the three will be the most appropriate?
