Reduced
Gravity
Pressure
difference between A and B:
DP = r2 * g * h
Pressure
difference between A and B:
DP = (r2 - r1 ) * g * h
r2
r2
Case A
Case B
The adjustment
process in Case B is exactly the same as in the Case A, except the gravitational
acceleration is reduced to a value g’, where
buoyancy force =
density difference * g
