Question #5 (Medium): Work Required to Pump Water Out of a Tank in the International
When the units is in the International metric system, then water density of is used. Since
mass in does not include gravity, it needs to be multiplied by to get the force.
Determine the work required to empty the spherical tank by pumping the water to the top of the tank.
The unit is in meters, so water density of is used instead of .
