re: What forces the water out?

DALeffler — 3/10/2006 3:38:33 AM (archived)

Hydrostatic pressure?

Take a pipe capped on both ends that's completelty filled with water and add heat. Even a couple degrees temperature rise will cause pressure in the pipe to skyrocket.

The rule of thumb I was learned on was 1 degree delta T (F) in a completly filled water pipe = 100 delta Psig.

Why this is, I dunno.

        Enceladus probably was much larger in the past... - REB - 3/9/2006 10:20:52 PM

        That is the main reason I think Enceladus is basically a large drop of water with an icy crust. - REB - 3/10/2006 1:07:48 PM

    - Looks like that's not it: NASA's Cassini spacecraft may have found evidence of liquid water reservoirs that erupt in Yellowstone-like geysers on Saturn's moon Enceladus. (n/t) - Buck Galaxy - 3/9/2006 5:45:44 PM
