a balance for finding the weight of an object submerged in water in order to determine the upthrust on it and thus determine its relative density
- Hydrostatic pressure
hydrostatic pressure (hī’drə-stāt’ĭk) The pressure exerted by a fluid at equilibrium at a given point within the fluid, due to the force of gravity. Hydrostatic pressure increases in proportion to depth measured from the surface because of the increasing weight of fluid exerting downward force from above.
