Physics Interview Question:
What is neutral buoyancy?
Submitted by: AdministratorBuoyancy is the net upward force experienced by an object submersed in a fluid. Pascal's principle dictates that fluid pressure on an object increases with depth, so there is greater pressure on the bottom of the object than the top, resulting in a net upward force. When an object's buoyancy is greater than its weight, the object will float.
An object with neutral buoyancy has a density such that when it is fully submerged the upward force due to buoyancy is exactly equal to the downward force due to the weight of the object.
In pure water this is a density of 1000 kg/m3 (1kg/litre)
In seawater, this is a density of about 1025 kg/m3 (1.025kg/litre)
