oh ok then floatie, im at work now don't push it :lol: and yes don't be mad :eusa_doh:
oh ja before I forget, must it be mono, flouro, braid or nanofil??

@Flaotie

How is it rigged? Texas, mojo, carolina, drop shot?
How old is the reel?

hat, coat, door :eusa_boohoo:

Water temperature also affects the speed at which objects sink

altitude of the lake too maybe Kassie? im not too clued up

True that. Higher altitude generally has lower air pressure.
Lower air pressure = lower density

gezz now you okes are getting too technical for my liking. :eusa_wall:
And you starting to sound like the Americans :eusa_hand:

Not quite true - water has 1bar pressure at 1m depth, 2bar at 2m etc. Baro pressure does not come into affect with water.
Water clarity will also play a role :eusa_angel:

But being in a different hemisphere will... go figure that one out.

The sink rate of ice cold beer = Fekking Quick!

No - JFZ's right. Complete BS from my keyboard. :eusa_liar:
You cannot compress liquid state water (well you can but its almost impossible to any great degree and it's one helluva effort for almost immeasurable results)

Floatie, ignore all these okes, here's what you need to know when you bath with your tackle:

I am going to talk about a spherical object whose density is greater than that of the water so it will sink and not just float. The maximum rate of descent in water is similar to that for air. It occurs when the force of drag equals the force of gravity so the object that is sinking has 0 net force and therefore no acceleration. The drag force depends on the speed of the object, the faster the object is moving the greater the drag. The object starts with an accleration g (gravity) and starts to sink. The rate of descent also depends on the buoyant force of the water meaning that if the object is too light it will float. So the forces acting on the object are gravity pulling it down, the buoyant force pushing it up and the drag force slowing it down. Eventually the drag cancels out the effect of gravity and the object will have no net force and no acceleration so will continue to sink but with a constant speed.

In more mathematical terms, for slow moving objects the drag is approximately proportional to the speed and can be written as:
F = drag force = -b*v

"b" is a constant that depends on the shape of the object, the density of the fluid, etc. "v" is the velocity of the object. It is negative because it acts in an opposite direction to the velocity.

All detail are provided on the picture.

The maximum rate of descent is given by:

(V*g/b)(p - 1000)

V is the volume of the object
p is the density of the object
1000 kg/m^3 is the density of water
g = acceleration of gravity = 9.81 m/s^2
b = the constant mentioned above

Assume a perfect sphere! Sounds like science to me.

Thanks Riprap I got it I will do all the calculations for Floatie!

Is jy mal!!! We catch bass we dont launch rockets or build submarines ok maybe Navrik but still :? :blue-biggrin:
