I'm putting A LOT of my eggs into that basket, the MTV basket. I'm also thinking about getting a gun, and dealing crack. Being a crack dealer. Not like a mean crack dealer, but like... like a nice one. Kinda friendly like, "hey, what's up guys? Want some crack?" I'm just waiting on those two things to flesh themselves out. |

Post Number: 1724 Registered: Sep-06 | u have to calculate: 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: Q = K(A P/c) and then you will have your answer! |
