If we have a water filled horizontal pipe on seabed with 200 bar in it.
And boat with a flexible downline is connected to the pipeline in 100m of water depth.
a) If the vessel bobs up and down by 5m I think that the pressure in the pipeline read at vessel changes by 0.5 bar each way, due to...
I understand that vapor pressure is independent of initial pressure, and depends only on temperature.
However, is this true of a non ideal gas at high pressures?
(I am specifically interested in the vapor pressure of a meg/water mixture at approx. 100 bar),
