In Problem 9 what would be the effect on the line flow rates and node pressures if a device with a pressure-drop relationship of were placed in line 6?
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. _
