Example 10.17 Problem The water in a tank weighs 675 pounds. How many gallons ,does, it hold? Solution Water weighs 8.34 lb/gal; therefore: 675 lb = 80.9 gallons 8.34 lb gal Example 10.18 Problem A liquid chemical weighs 62 lb/cu ft. ,How much does, a 5-gallon container of it weigh? Solution Solve for specific gravity; to obtain lb/gal, multiply by 5.

We ,need, an operational unit that can be reasonably studied and will help explain all or most of the characteristics of the lake. The lake is primarily dependent on the water in the hydrologic cycle, and the most useful definition of the lake ecosystem is the lake and its watershed because the watershed defines the terrestrial sources of the lakes water (Figure 1-1).

Sugar Plant [1250 ,ton, per day crushing] A Sugar Plant or sugar refinery is a refinery which processes raw sugar into white refined sugar. Many cane sugar mills produce raw sugar, which is sugar that still contains molasses, giving it more colour (and any associated nutrients) than the white sugar which is normally consumed in households and used as an ingredient in soft drinks and foods.
