Yes, I posted a formula awhile back that calculated a systems efficiency (power and SPL used incalculating this).
I have since forgot this formula...but you can search on this forum for it. I believe the thread was titled something like "Wanna know oh efficient your system is?"
I was working on some stuff in physics when i posted that thread...I cant remember all of it now though.
BTW...i am Marshall. I just changed my name on this forum to Canaan while back. (all my friends now me as Canaan...its was getting confusing w/ me posting as Marshall)
var deltaX = x2-x1; var deltaY = y2-y1; then convert theta from radians to degrees.
if that doesnt work try this
"Find x > 3 such that
ln(x) < x^(0.1)"
you have to understand the theory of operation: Q = (P1 - P2) r4 / 8cL Q = Volumetric Flow Rate P1 = Static pressure at the inlet P2 = Static pressure at the outlet r = Hydraulic Radius of the restriction c = (eta) absolute viscosity of the fluid L = Length of the restriction
Since , r and L are constant, the equation can be rewritten as:
