Design calculation is performed according to coal information and boiler parameters to determine fluidization velocity, bed material height (usually the height of the overflow port), and the air distributor area. This includes rivers, streams, drainage channels, waterways, navigation canals, irrigation canals and any channel conveying water. 644 0 obj<>stream design of lined canals” (First revision) discusses various methods for relieving uplift pressure below canal linings. 0000002024 00000 n major and medium canal waterways a concentration of flow may be to the extent of 15% to 25%, depending on the local physical conditions and the remedy would be to adopt the design intensity of flow with an increase of 15% to 25% over the average “q” value. However, before lining of a canal is decided, techno-economic justification for the same should be established. Same section may be adopted for a group of adjacent outlets if variation in discharge is nominal. The 20th week Measuring flow in open channels (weirs) Broad-Crested and Sharp-Crested Weirs Weirs are overflow structures that alter the flow so that: 1.
