Question

Shown below are the HGL and EGL for a particular flow system. Assuming a steady flowrate, answer the following questions. a. Is there any hydraulic machinery in the system? If so, where and what type? h. Is the pipe prior to A larger or smaller than that immediately after A? e. Is there a free surface, such as a reservoir, in the system? If so, where? d. Is the pipe between B and C rougher or smoother than that between A and B? e. Which of the following is most likely to be located between D and E? A gradual contraction, an abrupt contraction, a gradual expansion, or an abrupt expansion. f. What likely exists at B?

Explanation / Answer

a)There is a hydraulic machinery like pump in the system at point A

b)prior to A pipe diameter is smaller to maintain steady flow because of pump presence

c) free surface is present after point E

d)pipe between B and C is rougher than A and B

e)between D and E gradual contraction because velocity head is increased

f) at point B there may be pressure released valves
