Water flows into a node at a flow rate Q = 0.35 ft/sec and leaves the node through three parallel pipes which converge at a subsequent node. Determine: a. The flow rate in each pipe if they have the characteristics shown in the table below... (Ans. Q = 0.081 ft/sec, Q = 0.164 ft/sec, Q3 = 0.105 ft/sec) Pipe L(ft) D(in) f 1 90 2 0.020 3 2 120 3 0.025 5 3 180 2.5 0.022 1 b. The proportion of flow through each pipe c. The new flow rate through each pipe if the incoming flow rate to the node decreases to 0.25 ft/sec
