AI Thread Summary
Electroosmotic micropumps utilize electroosmotic flow to transfer liquids from one location to another. A reservoir is essential as it supplies the liquid needed for the pumping process. Without a reservoir, there would be no source of fluid to move through the microchannels. The reservoir can be as simple as a container where liquids are pipetted in. Understanding the role of the reservoir is crucial for the effective operation of electroosmotic micropumps.

Hi!
This is about electrosmotic micropumps. I don't understand why there is always a reservoir and what is the point of this reservoir on the pumps?
Can someone explain it to me?

thank you!

Electroosmotic flow is just the mechanism used to transfer a volume of liquid from point A to point B. Electroosmotic pumps use this principle to pump fluid into a microchannel or another chamber. You still need to provide the liquid that gets moved, which is why you'd need a reservoir of some sort, even if you just pipette stuff into the 'reservoir'.

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...

Thread 'Where is my curb stop?'

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter. Is that knob that I drew a red circle around my meter...
