In Problem 9, what would be the effect on the line flow rates and node pressures if a pump with the head flow-rate relationship
were placed in line 10?
Problem 9
Determine the flow rate in each line and the pressure at each node for the system shown in Fig. P1-9. The Hazen-Williams coefficient.is 100, and the pressure at node A is 88 psig. Pipe lengths and diameters are given in the following table. _
