A siphon spillway of constant rectangular cross section 4 m wide
x 2.5 m high has configuration as shown in Figure 8. The total
length of the siphon is 80 m. Various loss coefficients are: inlet
0.12 outlet 1.0 o (bend loss coefficient) 0.75 friction factor
0.018 Determine (a) the maximum discharge, (b) whether cavitation
would occur for that discharge, and if so, the safe discharge for
avoiding cavitation, and (c) the required constriction of the
outlet section to restrict that discharge.
