Homework Help Overview

The discussion revolves around a problem involving valves and sealed tanks, specifically focusing on the transfer of water between two tanks. Participants are exploring the mechanics of how to achieve this transfer given the constraints of the setup.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants are questioning the necessity of turning on the pump and whether opening the valves is sufficient for transferring water. There is also speculation about the direction of the pump's operation and the implications of the tanks being sealed.

Discussion Status

The discussion is ongoing, with various interpretations being explored. Some participants suggest simply opening the valves, while others express confusion about the setup and the role of the pump. There is no clear consensus, but multiple perspectives are being considered.

Contextual Notes

Participants note that both tanks are sealed, which raises questions about air backflow and the efficiency of water transfer. The problem's specifics regarding the pump's operation and the potential for additional parts are also under discussion.

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.
