Homework Statement
Water (n = 1.00 10-3 Pa·s) is flowing through a horizontal pipe with a volume flow rate of 0.029 m3/s. As the drawing shows, there are two vertical tubes that project from the pipe. From the data in the drawing, find the radius of the horizontal pipe.
Homework Equations
Q = πR^4(P1-P2) / 8nL
The Attempt at a Solution
0.029 = πR^4(0.045) / (8*10^-3 * .7)
solve for R, multiply by 100. However, i don't get the right answer...
What am i doing wrong? this seems like such a straightforward problem
