Question

Can I get a solution for this question? It's quite hard to solve.

Hydraulic and Energy Grade Lines ($7.8) 7.36 The HGL and the EGL are as shown for a certain flow system. a. Is flow from A to E or from E to A? b. Is there a pump in the system? c. Does the pipe at E have a uniform or a variable diameter? d. Does a reservoir exists in the system? Sketch the physical setup that could yield the conditions shown between C and D. f. Is anything else revealed by the sketch? EGL ae HGL EGL and HGL 1 ! D A B E Problem 7.36

Answer 1

a) The flow is from A to E as the EGL decreases from A to E.

b) The pump makes EGL and HGL jump upwards, Since the losses at section, D are negated by some effect that is the pump. So at D pump is present

c) At section E the lines are straight. Hence the velocity remains constant and hence the diameter of the pipe is constant.

d) At A reservoir exists
