A pump delivering 5000 g.p.m. of 60° F. water has a 16-in.-diameter suc- tion pipe and a 14-in. discharge pipe. The suction vacuum gage, which is 3 in.) below the pump centerline, reads 5 in. of mercury (below atmospheric pressure). The discharge gage, which is 18 in. above the pump centerline, reads 10.6 lb. per sq. in. ga. What is the head of the pump? The specific gravity of mercury is 13.6.
