Conclusions
-
1.
The design water velocity in conduits should be assigned with consideration of the linking structures and possible variation of the calculated expenditures.
-
2.
It is expedient to go for an increase of velocity with consideration of construction works and standard diameters of the conduit.
-
3.
Without violating the general principles of economic calculation, the design velocity in the conduit can be taken increased up to 10% of its value at Exmin.
