Figure out the weight of the device (ROV, submarine,etc), and then the weight of the water displaced. When they are equal, the device is neutrally buoyant. However, usually engineers create a ROV with a slightly positive or negative bouyancy, personally I perfer a positivly buoyant ROV because if you lose power or the tether is cut the ROV will ascend back up to the top.
A more simple answer is that when the gravity & buoyancy are equal it is neutrally buoyant
A rock sinks because it is not buoyant. Buoyancy is whether or not something floats in water. There are three levels of buoyancy; buoyant, neutrally buoyant, and not buoyant. When something is buoyant, that means it has a lower density than water, causing it to float. When something is neutrally buoyant, that means it has roughly the same density as water, causing it to float half way between the bottom and the surface. Finally, when something is not buoyant (like a rock), that means that it has a higher density than water, causing it to sink to the bottom.
neutrally buoyant
You can make a plastic bottle neutrally buoyant by adding just enough weight (like sand or rocks) to offset its natural buoyancy. This can be done by experimenting with different amounts of weight until the bottle neither sinks nor floats when placed in water.
they are neutrally buoyant. they have ballast tanks to achieve this
No, it sinks
Something that neither floats nor sinks, stay in the middle of the tank or water subject it's in. Exp: bamboo with a balloon neither floats nor sinks in the tank. It stays in the middle on the 4 gallon tank.
Willard Dow has written: 'A neutrally buoyant suspension system for underwater instruments'
no that never happens Yes.
A synonym for an object with neutral buoyancy is "neutrally buoyant."
100ltrs
what object will not sink or float but will stay suspended in the middle of water
If the weight of the object is higher than the buoyant force the object SINKS. And the opposite happens if the weight is lower than the buoyant force. If it is equal, the object neither sink nor float, it is neutrally buoyant.
