(a) Explanation Given data: The quantity of freshwater that flows over a falls per second is given as 600,000 gallons. Explanation: Write the expression for given quantity of freshwater that flows over the falls as follows. Given quantity of freshwater = 600 , 000 gal s (1) Write the conversion factor between hour ans second as follows. 1 hr = 3 , 600 s Rewrite the conversion factor as follows. 1 s = 1 hr 3 , 600 Substitute ( 1 hr 3 , 600 ) for s in equation (1). Given quantity of freshwater = 600 , 000 gal ( 1 hr 3 , 600 ) = 2 , 160 , 000 , 000 gal hr Rewrite the expression as follows. Given quantity of freshwater = 2 , 160 , 000 , 000 hr gal Convert the gallons of water in terms of tons by the following steps. Step-I: Convert the gallons of water in terms of cubic feet. Step-II: Convert the measured cubic feet of water in terms of pounds. Step-III: Convert the measured pounds of water in terms of tons. Conversion of gallons of water in terms of cubic feet: Refer to the Table 9-7 in the textbook for the Conversion factors for Capacity in the English system. From the table, write the conversion factor between cubic feet and gallon as follows. 1 cubic feet ≃ 7.48 gal Rewrite the conversion factor as follows. 1 gal = 1 cubic feet 7.48 Multiply with ( 2 , 160 , 000 , 000 hr ) on both sides of the expression. ( 1 gal ) ( 2 , 160 , 000 , 000 hr ) = ( 1 cubic feet 7.48 ) ( 2 , 160 , 000 , 000 hr ) Simplify the expression as follows. ( 2 , 160 , 000 , 000 hr ) gal = ( 1 ft 3 7.48 ) ( 2 , 160 , 000 , 000 hr ) = 288 , 770 , 053.4759 hr ft 3 Conversion of measured cubic feet of water per hours in terms of pounds per hour: Refer to the Table 9-7 in the textbook for the Conversion factors for Capacity in the English system (b) To determine To find: The time required to fill the freshwater to the building.
