1. Water is flowing through a network of pipes (in thousands of cubic meters per hour), as illustrated in the diagram below. The direction of water flow is indicated by arrows, and pipe junctions are represented by the letters A, B, C, D, E, and F. A В з00 С х, 500 х, 500 D 450 E x, F *. The six linear equations for the flow rates x1, x2, X3, x4, x5 and æe are given by: + x3 = -500 = 500 - 2A = 300 = 300 - I5 = 300 - I5 = 300 (A) (B) = 50 Ts = 50 + x7 = 450 + a7 = 450 a5 - x6 + x7 = 0 2z + a6 - xT = 0 + x3 = 500 + x3 = 500 - x4 = 300 - x4 = 200 - I5 = 300 - I5 = 300 (D) F50 = 50 +#q= 450 +27 = 450 s - r+x7 = 0 az - 26 + x7 = 0 = 500 - 24 = 300 i+ 25 = 300 (E) = 50 + x7 = 450 a5 - a6 + x7 = 0
