Appendix D – Problem 10

D.10 In the previous example, we considered a scenario where the utility had replaced burst PVC pipes (low celerity) with DI pipes (high celerity). Suppose you are working with another water utility where short sections of high-celerity asbestos-cement (AC) pipes (in a predominantly AC pipe network) were replaced by the lower-celerity PVC pipes.

Would it be necessary to update the model by carefully dividing the longer pipe elements into multiple elements accounting for all sections of replaced pipes, for dependable surge analysis results?
