A certain amount of hydrogen, when placed under oceanwater, will be compressed and become smaller and less bouyant the deeper it is placed underwater. Does anyone know the method or formula for figuring how much at what depth, for example, one pound of hydrogen at one foot deep, then ten then one hundred?
PVT is the standard atmospheric conditions
P1 - pressure due to column of water
i.e. density of water x height of the water column x 9.8 (gravity)
Let say the T=T1 then use can easily find the final compressed volume.
You are right if you compress the given sample it will become less buoyant but less compare to what? even if you liquify the hydrogen or lets say you use oil in place of compressed hydrogen, these will remain buoyant irrespective of the applied pressure.
under the similar conditions, hydrogen will always be less buoyant than oxygen
This appears to contradict intuition.
The buoyant force on an object equals the weight of the fluid displaced by the object, and since 1 lb of oxygen occupies less volume than the same mass of hydrogen, under equal P,T conditions, the seawater volume displaced by oxygen is smaller, and so is the buoyant force.
Thus, I"ll be grateful for an explanation to descry my conceptual error.
