发帖数: 4 | 1 ft, just an undergraduate fluid mechanics problem
dp*D/l = f*den*v^2/2;
dp: pressure difference;
l: length of pipe
D: diameter of pipe
f: friction factor, function of Reynolds number;
den: density of fluid;
v: velocity.
for the problem to get flow rate, dp*D/L, den should
be given, then assume a v to get f; and do several
iterations. |
