Find the forces in the members IH, IC, and CD of the truss.

Question

The system in Fig. consists of 1200 m of 5 cm cast-iron pipe e=0.26mm, two 45° and four 90° elbows, a globe valve, and a sharp exit into a reservoir. If the elevation at point 1 is 400 m, what gage pressure is required at point 1 to deliver 0.005 m3/s of water into the reservoir? U= 10-6m² 1 * sec -, K 45° elbows= 0.2, K 90° flanged = 0.2, K globe valve 10, K Sharp exit=1 G Elevation 500 m 45° Open globe 45° Sharp exit
