Re: Physics and buoyancy question
Simple calculation will be figuring out the amount of water displaced.
When you know that you will already know the bouyant force of the boat.
The volume that is displaced by the boat multipled by the density of the water you are operating in (salt or fresh) will give you the bouyant force.
Subtract this from the "air" weight...
If your bouyant force is equal to or greater than 8 lbs you don't need flotation....if it is less...you can add off-board flotation...(to increase the amount of water displaced...)
It is really pretty simple... the "weight" of the fluid displaced is equal to the bouyant force....
To float... bouyant force must be equal to or greater than the dry weight.
