Buoyancy is not a characteristic of fluid but rather it is the upward force on the object that the fluid provides. The only way a fluid could have an effect similar to no buoyancy is if it couldn't provide an upward force great enough to provide the object to stay on top of the fluid.
All liquids, and gases are fluids.
The ability to float is called buoyancy. It is the upward force exerted by a fluid that opposes the weight of an object placed in the fluid, allowing it to stay afloat.
In zero gravity, buoyancy would not be present as there is no gravity to create the force that causes objects to float in a fluid. Objects would not experience an apparent weight loss or loss of buoyancy in zero gravity.
A fluid is a substance which can flow, so some examples of fluids would be coffee, tap water, and steam.
Viscosity is a fluids resistance to flow. A high viscosity fluid would be thick, a low viscosity fluid would be thin.
Gravity is needed for buoyancy as if there was no gravity then there would be no need for buoyancy, the need for buoyancy is to counteract the pull of gravity so you can stay at the surface of a liquid such as water. If there was no gravity then there would be no need to counteract it. I hope this the answer you needed. What if there is a ball of water in space and a cork made dof wood is inserted carefully into the ball. Would it 'rise' from the center of the ball towards the surface or not???
Not at all. Buoyancy depends only on the volume of an object in fluid. If buoyancy depended on mass, we would expect that every 1-lb stone should float, whereas every 10,000-ton ship should sink.
F(buoyant) = -pVg p = density of the fluid V = volume of the object g = standard gravity on Earth (~ 9.81 N/kg)
For an object to have neutral buoyancy, its density must be equal to the density of the fluid it is immersed in. This means that the weight of the fluid displaced by the object is equal to the weight of the object itself, resulting in no net force acting on the object, allowing it to remain suspended in the fluid.
because you dont want them to become fluid over loaded
Ideal FluidsIn compressibleIt has zero viscosityNo resistance is encountered as the fluid movesReal FluidsCompressibleViscous in natureCertain amount of resistance is always offered by these fluids as they move
The most common method of classifying fluids are through a measure of viscosity; how close to being soilid. Peanut butter would have a very high viscosity, where gasoline or water are very low. Fluids can also have different densities; adding bubbles to water can change the density of the fluid, sometimes leading to the sinking of sea vessels due to a drop in buoyant force.
