It is well known that in a parallel pipeline system if you increase the diameter of those parallel pipes, it increases the capacity of the pipe network. But if we increase the length of the parallel pipes, what will be the impact on the capacity of the system happen? O The flow capacity of the parallel system will remain the same. O The flow capacity of the parallel system will decrease. O The flow capacity of the parallel system will increase. O It is unknown, depends on the parallel pipe diameter.

For pipes in parallel, what condtions must be satisfied? O Flow is the accumulation of the flows throughout each branch pipe Head loss is a sum of the total (major and minor) head loss from entrace to exit The total head loss (major and minor) is equal throughout each branch pipe O The flow through each pipe is the same

Two reservoirs, A and B, are connected together by the two pipes with a pump between them. Assuming that the head loss in the pipes is given by hi = 0.015(L/d)(V/2g), where "L" is the length of pipe in feet and "d" is the pipe diameter in feet, determine (a) the velocity in each pipe, (b) the head added by the pump, and (c) the horsepower that must be supplied to the water to pump 2.5 cfs from the lower to the upper reservoir? El 140 ft B A El 90 ft L: = 2000 ft d: = 8 in. El 40 ft --- L; = 1000 ft d: = 8 in.
