How do you use buoyancy?
Buoyancy is what keeps a boat floating on the top of the water. Buoyancy is what makes a helium balloon float in the air.
How do concrete boats float?
This all depends on buoyancy of the liquid the boat is in, and the density (therefore the mass and volume) of the concrete boat.
What is buoyancy and how does it affect a blimp?
buoyancy is a measure of how well an object will float in a given medium, eg: a boat in water. similarly for a blimp, the blimp is the object, the air is the medium. if it is not buoyant enough, it will not 'float' in the air, aka fly
What is the Buoyancy of a gallon container?
1 gallon of air would have the buoyancy equal to the weight of 1 gallon of the fluid it is displacing. According to http://www.ehow.com/how-does_5145137_steel-but-steel-boat-float.html Example: 1 gallon of water weighs approx 9 (lbs) therefore 1 gallon of air would have 9 gallons of Buoyancy.
Why doesn't a ship sink to the bottom of the ocean answer with something about density?
It's buoyancy since the air in the bottom of the ship keeps it afloat. The air is lighter and less dense, so it does not sink into the water. The amount of air must be adequate to the boat's size. Bigger boats need more buoyancy.
How does buoyancy affects a boat?
Buoyancy affects a boat by keeping it "on" the water, not "under" the water.
How does an iron boat float?
Buoyancy!
How can buoyancy be demonstrated?
buoyancy can be demonstrated if you float something because buoyancy is when something floats for example a boat floating in water
How do you use buoyancy?
Buoyancy is what keeps a boat floating on the top of the water. Buoyancy is what makes a helium balloon float in the air.
How do you use the buoyancy on a boat?
By putting it in water.
What is the fullform of boat?
Buoyancy Operated Aquatic Transport
What does the hull do on a boat?
Basically, the hull on a boat keeps out the water, and displaces the water to create buoyancy, which enables the boat to float.
What is the easiest way to make a cardboard boat go faster?
put a point in the front of your cardboard boat and paddle really fast but pace yourself
How do you calculate center of buoyancy?
B=(pb-pt)a
How do you calculate the amount of foam you need to support a dock?
Mass of dock. Initial buoyancy. Buoyancy of additional foam.
What force does a boat use?
up thrust gravity buoyancy density
Does gravity allow a boat to float on water?
Without gravity, a boat wouldn't be able to float on water, so yes, gravity allows a boat to float (as well as sink into) water. A boat floats from buoyancy force. The buoyancy force is from the volume of water it displaces with it's shape below the water. The buoyancy force is equal to the volume of water it displaces multiplied by 62.4 lbs. per cubic foot (the density of water). So if the boat displaces 20 cubic feet of water with it's hull or shape it can hold 20 x 62.4 = 1248 lbs. of self weight plus cargo. Obviously there should be a factor of safety on that. In summary, a boat needs two things to float on water: Gravity and buoyancy force. Gravity keeps the boat on the water in the first place, but the buoyancy force is the actual thing that keeps the boat afloat. Technically, it is the buoyancy force that allows a boat to float, but if you want to get really technical, it is gravity in the first place that allows a boat to float on water.
