How can I solve this problem with valves and sealed tanks?

AI Thread Summary
The discussion centers on solving a problem involving valves and sealed tanks for transferring water. Participants emphasize that opening the valves is essential to facilitate the transfer, as the pump alone cannot function effectively with both tanks sealed. There is confusion regarding the pump's operation direction and the implications of the tanks being sealed, which would hinder water flow without air backflow. Suggestions include turning on the pump and even creating siphons, but ultimately, the consensus is that opening the valves is the simplest solution. The conversation highlights the tendency to overcomplicate straightforward problems in fluid dynamics.

The problem just asks how to transfer the water, right?
Frankly "turn on the pump" is jumping up and down and waving at me...
Is there a part b? Like, complete part a, and find some value?

:rolleyes: It is the wisest thing to do.

Or build a http://en.wikipedia.org/wiki/Siphon" . :smile:

Why do either of those things? The problem is to transfer water from the upper tank to the lower. I would assume that the pump would be there to go the other way. Answer- open the valves!

I guess it's a perfectly valid question if two out of three PF members got it wrong!

1] If the pump were turned on, the valves would still be closed.
2] We don't know which way the pump pumps.

Answer - as HoI points out: open the valves!

[EDIT]
Hm. It does specifically say both tanks are sealed. Without backflow of air, it would take a very long time to transfer.
Turning the pump on would speed the process.

Ummm...so just open the valves huh? Mother#%#@$@! Why do i tend to complicate things? %^$@$$#@#(&%
 
Open the valves and punch holes in both tank tops.
