Solution: r = D/2 = 50 mm = 0.050 m; h = y = 20 mm = 0.020 m; = 2 arccos [ (0.050 0.020)/0.050) ] = 1.85 radians A = [ 0.052 (1.85 Technical Supplement 14BScour CalculationsScour Calculations Purpose Scour is one of the major causes of failure for stream and river projects. It is important to adequately assess and predict scour for any stream or river design. Designers of treatments such as barbs, revetments, or weirs (that are placed on or adjacent to streambeds) must estimate the probable maximum scour during theSAGMILLING.COM .:. tools_pipelaunderSlurry service typically requires flows between 36 m/s to avoid depositing coarse solids. Higher velocity results in higher pipe wear. This geometry dictates a angle of 4.0 radians, 230.8°. and a halftop (b) dimension of 0.40 metres, 15.81". Hydraulic radius (Rh) of this geometry is 0.265 metres; 10.4".

The momentum of the stream flow is used to pump some of the water to a considerably higher level. For example, a stream falling 2 m below can be made to pump 10% of its flow to a height 12 m above.
