P10.16 P10.17 A circular corrugated-metal storm drain is flowing half
full over a slope 4 ft/mi. Estimate the normal discharge
if the drain diameter is 8 ft.
A sewer pipe has the shape of Fig. P10.21 and is constructed of unfinished concrete. The slope is 3 ft/mi. Plot
the normal flow rate as a function of depth over the full
range 0 y 7 ft, and determine the maximum discharge and maximum velocity. In Prob. 10.15, for finished concrete, determine the percentage of reduction in flow if the channel is divided in
the center by the proposed barrier in Fig. P10.15. How
does your estimate change if all surfaces are clay tile?
The trapezoidal channel of Fig. P10.17 is made of brickwork and slopes at 1:500. Determine the flow rate if the
normal depth is 80 cm. A trapezoidal aqueduct (Fig. 10.7) has b 5 m and
40° and carries a normal flow of 60 m3/s of water when
y 3.2 m. For clay til...
