how to caluculate buoyant force in accelerating fluids?..

suppose fluid is in the elevator accelerating by a then
buoyancy force=volume*density of fluid*efficient gravity
efficient gravity=[g-a]

Answer / guest

You can simply add the earth's gravitation to the
acceleration of the fluid (You should use vectorial
addition). After this you can again use Archimedes' law:
Fb = rho x (g+a) x Volume
Fb is now in the direction of (g+a)

how to caluculate buoyant force in accelerating fluids?..

Answer / homles

suppose if the liquid is accelerating upward in the elevator with acceleration 'a' then the weight of bod acts downward i.e mg and the pseudo force with respect to us when we are watching the elevator from outside the pseudo farce is -ma upward or ma downward then the total net force is equal to the buoyant force i.e m(g+a)
and is the reverse case for if the acclerating fluid downwards then the buoyant force is m(g-a)
