The 12 in diameter cast iron pipe is 2000ft long, the water surface is El 200 in the reservoir on the left B. El 175 on the right.
A. Find V and Q by hazen-williams for a new cast iron pipe (Chw=130) Neglect entrance, exit and local losses.
B. Using this computed velocity, and considering local losses, determine how much higher must reservoir B actually be to provide the same Q? Square entrance and exit. The sum of bend coefficients K=4.
C. Find the velocity at the vena contracta constriction. How much does HGL dip as water enters the pipe?
