Conclusions
-
1.
The optimal cross sections of tunnels (pressure and free-flow) and of steel conduits should be determined by means of exact equations for detailed design stages and by approximate equations for rough calculations.
-
2.
In the case of complex layout schemes with the presence of daily storage reservoirs it is not possible to use analytical methods of calculating the cross sections of tunnels and conduits.
-
3.
The possibilities of using equations for calculating optimal cross sections of cannais and flumes of hydroelectric stations are extremely limited.
-
4.
It is necessary to develop methods of optimizing power conduits, including both analytical and ordinary power-economic methods of their calculation.
