1. Water is pumped at a rate of 80 gal/min from a storage tank maintained at atmospheric pressure and discharged to an open channel at height z above the liquid level in the storage tank. The pipe has an internal diameter of 2.067 inches and the pump delivers 10 hp of shaft work. The friction loss in the pipe equals 0.09z ft-lbg/lbm. Calculate the elevation z. Density of water is 62.4 lb/ft³. (14 points)
