if i tell you that water displaced in terms of (Volume initial and Vfinal ) is Vf how would i be able (if you can) to calculate the weight of the boat?
That is buoyancy. That's what buoyancy is!alister718 said:Buoyancy has nothing to do with it?
http://en.wikipedia.org/wiki/BuoyancyIn physics, buoyancy is the upward force on an object produced by the surrounding fluid (i.e., a liquid or a gas) in which it is fully, or partially immersed, due to the pressure difference of the fluid between the top and bottom of the object. The net upward buoyancy force is equal to the magnitude of the weight of fluid displaced by the body.
No. Think about that a little more. Why would this tell you the volume of the boat? Most of the boat is not submerged! So the volume of water displaced is only the volume of the submerged portion of the boat...Math Jeans said:V_f would not allow you to know the weight of the boat, It would only allow you to know the volume of the boat. You must also know the material that the boat is made from in order to find the weight.
Yes, and...? How much upward force does the floor exert on you...?The displaced water dictates how much upward force is exerted on the boat.
No, no, no, no, no.alister718 said:if order to do this we would need to find the height of the boat that is not submerged
A boat designed to run fully-submerged is called a "submarine"...Math Jeans said:Sorry, I thougt that the implication was the the boat was fully submerged. My mistake.
The weight of the boat in water refers to the total weight of the boat and any objects or substances on board when it is floating in water.
The weight of a boat in water is different from its weight on land because of the buoyant force exerted by the water. This force counteracts the weight of the boat and reduces the overall weight when it is floating.
Knowing the weight of a boat in water is important for determining its stability and load capacity. It also helps in calculating the buoyancy and displacement of the boat.
The weight of a boat in water is typically measured using a scale or by calculating the displacement of the water when the boat is placed in it. This displacement is then converted to weight using the density of water.
The weight of a boat in water can be affected by factors such as the type and size of the boat, the number of passengers and cargo on board, and the density and temperature of the water it is floating in.
