P6.124 The three-reservoir system in Fig. P6.124 delivers water at
20°C. The system data are as follows:
D1 D = 15 in
L = 1200 ft P6.118 v L3 L1 2 | 8 in L1 1800 ft L2 D2 6 in D3 9 in 1200 ft L3 1600 ft All pipes are galvanized iron. Compute the flow rate in all
P6.125 Modify Prob. 6.124 as follows. Let all data be the same
except z3, which is unknown. What value of z3 will cause
the flow rate through pipe 3 to be 1.0 ft3/s toward the junction? Textbook Table of Contents | Study Guide 416 Chapter 6 Viscous Flow in Ducts z2= 100 ft p2 p1

P6.126 Modify Prob. 6.124 as follows. Let all data be the same
except that pipe 1 is fitted with a butterfly valve (Fig.
6.19b). Estimate the proper valve opening angle (in degrees) for the flow rate through pipe 1 to be reduced to
1.5 ft3/s toward reservoir 1. (This problem requires iteration and is best suited to a digital c...
