KI 1. Solve the hydraulic network shown in the figure below. Solving a hydraulic network requires finding the flows in all pipes and the pressures at each node. Solve the

network manually by constructing and solving a system of equations. Check your manual answers by constructing a computer model of the system and then performing a computer simulation of the model. You should use the EPANET computer program. P2 Does this system operate properly? If it does not, suggest changes so that the system operates at an acceptable level of service?
