| Abstract: | Based on the simulation computation and theoretical analysis, this paper demonstrates the rises of water hammer pressure in prime pipe, analyzes the influence of hydraulic friction to transient flow. An application of relative value of hydraulic friction per unit pipe length is discussed, which indicates the influence of hydraulic friction to transient flow. A practical example of the influence of hydraulic friction in penstock to transient flow of a hydropower station is given. |
