Steelhead impact?

How much pressure does an attacking steehead put on the leader at the moment it strikes? 20 pounds? 30? More? Less?

You have to multiple the velocity of the water vs. the movement/speed of the fish and divide that from the mass of water and weight of the fish. Then square root the swing speed and divide against the current velocity. the answer is 33.3334 lbs per a 15 lb buck in 4 ft deep of walking speed water at a water temp of 42 degrees f. Ok?

Actually it is 33.52 - do the math!!
Buncha' jokesters!

From physics class we learn that pressure is the force per unit area applied in a direction perpendicular to the surface of an object. And F=MA, where force is equal to mass X acceleration. More data are needed Kerry.
1. how large is the steelhead?
2. What is the steelhead's acceleration, not just its velocity, but change in velocity per second per second?
3. What is the tippet diameter?
4. What kind of knot connects the tippet to the fly, since we need to calculate the unit area?
5. At what angle is the steelhead approaching the point where the tippet connects to the fly? We need to caculate the perpendicular vector to calculate the pressure.
6. What is the swing speed of the leader at the point where it connects to the fly? A vector of that velocity is additive to the steelhead's acceleration.

The water depth and temperature don't seem relevant to this equation.

Good grief!

For christ sakes! You had me up until tippet diameter.

Water temp and depth effect density. This isn't rocket surgery, dumby.
Yeah, right. The changes in density will significantly affect the solution, won't it?
WW, they just gave me more meds.

More threads to follow as soon as they start to take affect...............

Freaking big ass steelhead SG. Say over 40 inches. Head of steam and breaks 12 pound flourocarbon clean.
I would think the water temp would affect the tensile strength of monofiliment, not much, but it would.
Anything...and I mean anything that breaks my leader and gets away is always a monster!
That's just the way it is...:)
Lots o meds if your saying 40"+ cause that is TOAD

sounds like your looking for an excuse to run heavier tippet. just do it!

For a freaking big ass steelhead, over 40"? The answer is obviously 42!

nice Douglas Adams drop!
KerryS, you must be doing something wrong. How are those meds working?
