【Abstract】 Drainage sewage water system is very important to a city or town. Drainage sewage water system design is related to many aspects,among which,hydraulic calculation is a very important content.Traditional hydraulic calculation is very complicated,the relation among each parameter is vague. So this paper infers 14 formulas. These formulas can make the relation among each parameter clear.According to formula 10,diameter(d)of circle sewage pipe can be easy obtained;according to formula 13,both sides(a,b) of retangle sewage pipe can also be got to.Lastly this paper still discusses how to define each parameter, and how to use these formulas.更多还原
