How do you calculate center of buoyancy?
B=(pb-pt)a
Is buoyancy a physical or chemical change?
chemical change
What is the formula for center of buoyancy of cylinder?
centre of buoyancy = 1/2 (y) centre of gravity = 1/2 (H)
What is center of stability and why must it be above a ship's center of gravity?
A ship's center of stability is known as the metacentre. If you add weight to the side of a ship the moment created will cause it will roll. There has to be a restoring moment otherwise the ship will capsize. This restoring moment is due to the change in the submerged volume, hence change in center of buoyancy. This acts at the 'center of stability' where BM(distance from center of buoyancy to metacenter) = Inertia/DisplacementPicture a model of a yacht with a large weight attached to the mast. Now move the weight onto the keel. Which one do you think has the best stability?
Why does the center of gravity and center of buoyancy always not in same position?
Center of gravity is supposed to act at the centroid of the body. while center of buoyancy is the center of gravity of fluid displaced . so they cant be at single point. if the body is completely submerged and homogenous then both cg and cb will coincide
When is the pontoon is naturally stable?
When the center of buoyancy is directly above the center of gravity a floating object is stable.
What are the types of buoyancy?
There are only three types of buoyancy. Positive, Neutral and Negative. Positive rises, neutral is in between meaning its in the center and negative sinks. Your welcome
What causes the buoyancy to increase or decrease?
Buoyancy force come from difference in density of the object and the surrounding. Buoyancy of the ship can change from the pay load inside its' space. More load per space reduce the buoyancy. For Balloon, buoyancy is change by increase temperature of gas inside to balloon since increase in temperature would cause gas to expand and had lesser density in its' cavity. In general, buoyancy increase or decrease by changing of density of the object or the surrounding medium.
What is a metacentric diagram?
A metacentric diagram is a vessel (ship) stability diagram that shows the relative positions above and below the metacenter of the center of buoyancy and the center of gravity, respectively. Use the link to the Wikipedia article to view one and see how it looks. Follow along and see how it works. When a vessel floats in water, its center of gravity is below its center of buoyancy. That allows gravity to pull down on buoyancy from below the bouyancy to pull up on gravity from above (if it is permitted to say it that way). If the center of buoyancy slips below the center of gravity, the vessel will roll over. Visualize that. And the closer the two centers are, the less stable the vessel. That is, the more prone to rollover it is. The "sweet spot" between the centers of buoyancy and gravity is the metacenter. It's important in evaluating a ship's stability.
What affect provided by water aerobics helps make the exercise beneficial?
Buoyancy
Why the center of pressure of a submerged body lies below the center of gravity?
The upward thrust which the surrounding fluid exerts on an object is referred to as the force of buoyancy. This thrust acts through the centroid of the displaced volume, referred to as the centre of buoyancy. The centre of buoyancy is not the same as the centre of gravity which relates to the distribution of weight within the object. If the object is a solid with a uniform density exactly the same as water and the body is immersed in water the force of buoyancy will be exactly equal to the weight and the centre of buoyancy will be the same as the centre of gravity. The object will be in equilibrium with the surrounding fluid.
Does increase pressure in a tank increase its buoyancy?
no, it will not, in a compressible gas, the contents will increase in density, thus reducing its buoyancy. in an incompressible liquid or solid, no noticeable change will occur.
