(a) Solve the following network (see Fig. P1-19). The Hazen-Williams coefficient is 110.
(b) Filters with a head loss of 25.0Q2 are placed in the lines shown. A pump is placed in line 9. Find the required increase in head of the pump in order that 2.0 cfs flows through the line containing the pump. If the pressure at node A is 120 psig, find the pressure for the case at node I.
