Derive an expression for the maximum velocity for circular pipe and fixed
parallel plates.
Example (1-6): A pumping plant forces water through a 600 mm diameter main, the
friction head being 27 m. In order to reduce the power consumption, it is proposed to
lay another main of appropriate diameter along the side of the existing one, so that the
two pipes may work in parallel for the entire length and reduce the friction head to 9.6
m only. Find the diameter of the new main if with the exception of diameter, it is
similar to the existing one in every respect.
A pipe (f = 0.015) has a diameter of 250-mm and 150 m of length is connected in series with another pipe (f = 0.02) having a diameter of 200 mm and 200 m of length. Calculate the diameter of an equivalent single pipe of length 350 m and friction factor of 0.025
