Vent Way Calculations

The document calculates vent way dimensions for a weir with a length of 62.3 meters and discharge of 50.334 cubic meters per second. It determines that two vents of size 6.6 meters by 2.2 meters would be required, with a velocity in each vent of 1.73 meters per second.

VENT WAY CALCULATIONS :

Length of Weir L= 62.3 metres

For BC weir Q = Cd L H^3/2


1.70 X 62.3 X (0.609)^3/2

Discharge = 50.334 cumecs

Assumed Velocity in the Barrel = 1.80 m / sec

Area Required = Q / V = 27.963 Sq.mt

Considering a Vent size of 6.60 m x 2.20 m.

No.of Vents required = 1.926 no.

say 2 no.s

Velocity in the vent = 1.73 m / sec

Provided Vent size of 6.60 m x 2.200 m.

No.of Vents Provided 1.926

say 2 no.s

Velocity in the vent = 1.73 m / sec
