Task 27 Determine the diameter d of a horizontal pipeline of length l, which should pass liquid W in the amount of Vc at a temperature T = 20 0C. The pressure at the beginning of the pipeline N. The pipeline is made of M material.
Indication. As an initial approximation, take the value of the diameter calculated by the Poiseuille formula for the laminar flow regime of the fluid.
l = 580 m
W-water
Vc=75·103 m3/s
T=20S
H=36 m
M - aluminum
