The force of a fluid that pushes an object up is called?
Buoyant force. It is the upward force exerted by a fluid on an object submerged in it, which acts in the opposite direction to the force of gravity.
What is the name of the force in water?
Several forces: # hydrogen bonding # bouyancy # surface tension # plus dynamic forces, depending on the circumstance.
Is bouyancy a downward force exerted by a fluid on a body placed in the fluid?
No, buoyancy is an upward force exerted by a fluid on a body placed in the fluid. This force is equal to the weight of the fluid displaced by the body, according to Archimedes' principle.
Who discovered bouyancy force?
Archimedes, a Greek mathematician and scientist, is credited with discovering the buoyant force while taking a bath. He realized that the upward force acting on an object immersed in a fluid is equal to the weight of the fluid displaced by the object.
What force in fluids described by Archimedes'principle allows objects to float?
The buoyant force, according to Archimedes' principle, is what allows objects to float in fluids. This force is equal to the weight of the fluid displaced by the object, pushing it upward and counteracting its weight.
What does bouyancy mean?
bouyancy- force of weight of gas fluids.
What is the definition of bouyancy?
Bouyancy determines whether an object sinks or floats.
Why dosent a ship sink?
The bouyancy of the vessel keeps it afloat. As long as the force of bouyancy is larger then the mass of the ship it will stay afloat.
Does the make up of a liquid affect bouyancy?
Yes, it depends on the make up of its molecules. For example oil drops float on water due to its make up.

What is the bouyancy of a 55 gallon drum?
A standard 55-gallon drum has a maximum theoretical buoyancy of approximately 459 lbs (208 kg) when fully submerged in freshwater. However, in practical applications like building a floating dock or raft, the usable buoyancy is significantly lower to ensure stability and safety. Theoretical vs. Usable Buoyancy While the total displacement is fixed by the drum's volume, how much weight it can actually support depends on your safety goals: Theoretical Maximum (100% Submersion): ~459 lbs (208 kg). At this weight, the drum is entirely underwater and provides no additional lift to keep a structure above the surface. Recommended Working Load (50–75% Submersion): 230–345 lbs (104–156 kg). For a stable floating structure, it is standard practice to use only a portion of the drum's total buoyancy. This prevents the "raft" from sitting too low or tipping easily. Key Calculation Factors The exact lift a drum provides is calculated based on the weight of the water it displaces minus its own weight: Displaced Water Weight: 55 gallons 8.34 lbs/gal = 458.7 lbs. Drum Weight (Dead Weight): Plastic Drums: ~23–25 lbs (10–11 kg). Steel Drums: ~40–60 lbs (18–27 kg). Net Buoyancy (Submerged): Subtract the drum's weight from the displaced water weight. For a plastic drum, this leaves about 434–436 lbs of net lift. Environmental Variations Freshwater vs. Saltwater: Saltwater is denser ( 64.3 lb/ft ) than freshwater ( 62.4 lb/ft ), providing roughly 5% more lift (approx. 480 lbs total buoyancy). Temperature: Water density decreases as it warms. While negligible for DIY projects, a drum in boiling water would have about 4% less buoyancy than one in near-freezing water. Wikipedia Wikipedia +3 Summary Table Submersion Level Freshwater Lift (lbs) Freshwater Lift (kg) 100% (Maximum) ~459 lbs ~208 kg 75% (Standard) ~344 lbs ~156 kg 50% (High Stability) ~230 lbs ~104 kg ✅ Answer A 55-gallon drum provides a maximum buoyant force of approximately 459 lbs (208 kg) in freshwater, though for practical use, it is typically rated for 230–345 lbs to maintain stability and a safe waterline.
