Disclaimer: all of the following is mostly theoretical* So on Europa the pressure on the surface of the ice crust is 0.1 microPa
* Gravity on the surface is 1.314 m/s^2
* The ice crust is estimated to be ~10-30 km thick
* Beneath the crust is about 100 km of liquid water
* According to my professor's notes the pressure at the surface is 85 MPa - 200 MPa (dependent on the ice crust thickness)
So now my question may or may not be simple.
1) What is the pressure on the bottom side of the ice crust?
With that calculation I can use the following formula:
P(chosen depth) = P(bottom of ice sheet) + rho*g*depthNow a couple other questions:
2) I am assuming rho is constant because water is an incompressible fluid, is this a reasonable assumption?
3) the total depth is 100 km (approximately), is it reasonable to assume g, 1.314 m/s^2, is also constant?
Thanks, for your help guys (I'm off to see Fury with my buddy, I can answer any questions when I get back, feel free to make reasonable assumptions though)
