Engineering question

An architecture student approached me yesterday to ask me a very complicated question. How could he design a water pumping system in the moon. for a homework assignment I guess.

I’m not very confident in my engineering skills, after warning him I told him that I could only imagine a solution to the problem.

Water cannot exist as a liquid in the moon, because the atmosphere is nonexistent, so this water pumping system would need to include an inert gas. He could use a pump to introduce more gas into the tank and push the water out on the bottom, since the moon does have gravity this could work.

If this system was made for a moon station, it could even use air as the gas.

maybe ya’ll have a better solution.

Edit:



Thanks for pitching in!
