Wells drilled by a nonprofit called Water for South Sudan use a pump that can provide up to 5,500 gallons of water per day. Use this total amount to calculate the following:
How many gallons per day per person could the well produce for a village with a population of 850 if every gallon went to domestic use?
How does your number to Question 1 compare to to the 0.5 gallons of water per day accessible in some areas of the world?
How does your answer to Question 1 compare to the 80 - 100 gallons of water used per day by the average American?
If you only had the amount of water you calculated in Question 1 to use each day, how would you prioritize using it?

Air conditioners not only cool air, but dry it as well. suppose that a room in a home measures 5.0m×9.0m×2.4m . if the outdoor temperature is 30 ∘c and the vapor pressure of water in the air is 85 % of the vapor pressure of water at this temperature, what mass of water must be removed from the air each time the volume of air in the room is cycled through the air conditioner? the vapor pressure for water at 30 ∘c is 31.8 torr.
