Abstract
1,253,896. Flow control in liquid channels. UNIVERSITY OF QUEENSLAND. 20 May, 1969, No. 25548/69. Heading E1H. A weir with a crest B, Figs. 1 and 2, in an open rectangular channel permits a maximum flow-rate for a given depth of liquid, e.g. 10 ft., upstream thereof, the configuration of the weir being such that the width of flow at the free surface of the liquid is not greater than: where H s is the total specific energy of flow, h is the height of the weir above the bed of the channel, Q is the total rate of flow and g is the acceleration due to gravity. A contraction in a such channel, Figs. 3 and 4, permitting a maximum flow rate for a given depth of liquid upstream thereof has a configuration such that the width of flow at the free surface satisfies the above relationship saving that h has a negative value and is the change in the bed level between points H and J.
