Unformatted text preview: flow rate is 32 m3/s. If you stick your fingernail in the surface, as in Fig. P10.50, what half-angle wave might appear? A riveted-steel triangular duct flows partly full as in Fig. P10.56. If the critical depth is 50 cm, compute (a) the critical flow rate and (b) the critical slope. P10.46 P10.48 P10.49 P10.50 Replot Fig. 10.8b in the form of q versus y for constant E. Does the maximum q occur at the critical depth? A wide, clean-earth river has a flow rate q 150 ft3/(s ft). What is the critical depth? If the actual depth is 12 ft, what is the Froude number of the river? Compute the critical slope by (a) Manning’s formula and (b) the Moody chart. Find the critical depth of the brick channel in Prob. 10.34 for both the 4- and 8-ft widths. Are the normal flows subor supercritical? A pencil point piercing the surface of a rectangular channel flow creates a wedgelike 25° half-angle wave, as in | v v P10.47 1m | e-Text Main Menu | P10.56 P10.57 EES P10.58 P10.59 1m 1m For the triangular duct of Prob. 10.56, if the cr...
