The siphon spillway depicted below is operating at capacity with H = 9.5 m. The 45 m long siphon has a diameter of 1 m, a friction factor of 0.04, an inlet loss coefficient of 0.3, and a loss coefficient of 1.0. The crown of the siphon is 1.4 m below the reservoir level and 10 r away from the siphon entrance. Determine: a) the pressure at the siphon crown in KN/m². b) the discharge flowrate of the siphon in m3/s.

Question
The siphon spillway depicted below is operating at capacity with H = 9.5 m. The 45 m long
siphon has a diameter of 1 m, a friction factor of 0.04, an inlet loss coefficient of 0.3, and a
loss coefficient of 1.0. The crown of the siphon is 1.4 m below the reservoir level and 10 r
away from the siphon entrance. Determine:
a) the pressure at the siphon crown in KN/m².
b) the discharge flowrate of the siphon in m3/s.
