Engineers Without Borders, EWB, develops a water delivery system from a spring situated 1500 meters above sea level to a community located 1800 meters above sea level. 1. If the pipe connecting the spring and the village is full of water but not flowing, what is the pressure differential between the spring's end and the village end of the pipe? 2. What is the gravitational potential energy change that occurs when a liter of water is pumped from the spring to the village? 3. How much work is necessary to pump a minimum liter of water from the spring to the village?

Engineers Without Borders, EWB, develops a water delivery system from
a spring situated 1500 meters above sea level to a community located
1800 meters above sea level.
1. If the pipe connecting the spring and the village is full of water but
not flowing, what is the pressure differential between the spring's
end and the village end of the pipe?
2. What is the gravitational potential energy change that occurs when a
liter of water is pumped from the spring to the village?
3. How much work is necessary to pump a minimum liter of water from
the spring to the village?
4. If 3 liters of water are to be pumped every minute, what is the
smallest amount of power that must be imparted to the water W?
