供水

The model can be designed according to the absolute normal model scale or the distorted model scale, in consideration of the conditions of the test site and water supply capacity etc., this experiment designs model in the light of the distorted model scale . The distorted model scale can satisfy the similarity conditions of surge equation and water hammer equation.

试验模型可以设计成正态，也可以设计成变态，考虑到试验场地、供水能力等因素，模型按变态设计，模型比尺同时满足了波动方程和水击方程的相似条件。
