Computation of discharge through sluices - Under free flow condition
Unit 11 - Water distribution and control structures
Computation of discharge under free flow condition
The value of Cd for a monk sluice is however usually calculated by using the following equation.
Where,
Ke = Entrance friction co-efficient value of which may be taken equal to 0.5
f = Friction factor value of which for a concrete pipe may be taken equal to 0.03
L = Length of the pipe.
Free discharge through an open sluice as shown in Fig. can be computed by using the equation.
Ke = Entrance friction co-efficient value of which may be taken equal to 0.5
f = Friction factor value of which for a concrete pipe may be taken equal to 0.03
L = Length of the pipe.
Free discharge through an open sluice as shown in Fig. can be computed by using the equation.
Where,
b= Bottom width of the sluice
H1= Height of the water (on u/s side), above the top of the sluice opening or vent.
H2 = Height of water (on the u/s side) above the bottom of the sluice.
