Question #4 (Medium): Work Required to Pump Water Out of a Tank in US Metric
When the units are given in the International metric system (such as , ),
then: , where water density is .
But if the unit is given in the US metric system, the tank dimension is given in , and water density of
is used. Weight in does not need to be multiplied by the gravity of , because
Determine the work required to completely empty an aquarium that is long, wide, and
deep, using the fact that water density is .
The units are in the US me
