n 11.3 x 3 + 50.4 each steam-piston, = 421.08; and the equivalent effective pres-sure on pump-pistons, reduced to area ofsteam-pistons, is 46.5 x 0.384 = 17.86;so that the efficiency of the pumps, asmeasured by the pressure in the main, 17.86was = 0.847. 21.08 Results of duty trial, June 26, 27,… … 598 PUMPING ENGINES. Pressure under which the pumps delivered water, 54 + 2 — 10.5 = 45.5 lbs. per sq. in. Total revolutions of engines, 23,092. Effective area of pump-piston, 185.475 sq. in.; distance traveled by all pump-pistons per revolu-tion, 22 ft. Pounds of wood put into the furnaces, 532;…
