Design flow (maximum) MLD 49.5

Or litre/sec 572.9

Based on chart,throat width selected inch 18

Width of the flume mm 457.2

h2/h1 =0.7

h2(head of water D/S) m 0.47

Depth below the crest of the parshall flume weir m 0.328

Therefore liquid depth in the parshall flume channel m 1

Therefore, actual velocity in the channel m/sec. 0.477

Down stream of the parshall flume will be distributed between two SBR settling tanks by

providing a distribution chamber. 3 nos. sluice gates will be installed one each at the inlet of

the SBR unit and one at the bye pass.
