一、概述 (一)管道设计计算方法在管道设计计算中,决定管道系统中每一管段的特性参数有:截面积(或直径)、长度、流量、流速及阻力.通常,在管路布置好之后,即知道在管段长度的基础上,选择流量和流速,根据流量方程求得该管段的截面积或直径;由计算得出的管段截面积(直径)及流量或流速,通过查摩擦阻力线解图和局部阻力系数图表,求得该管段的阻力损失.将若干管段
I. Overview (I) Pipeline design calculation method In the pipe design calculation, the characteristic parameters of each pipe segment in the pipe system are determined: cross-sectional area (or diameter), length, flow rate, flow velocity and resistance. Usually, the pipeline layout is good. After that, we know that on the basis of the length of the pipe segment, select the flow rate and flow rate, and obtain the cross-sectional area or diameter of the pipe segment according to the flow equation; calculate the cross-sectional area (diameter) of the pipe segment and the flow rate or flow rate, and check the friction resistance line. Solve the map and the local resistance coefficient chart to determine the resistance loss of the pipe section.
