管路直径之最大流量表

管路直径之最大流量表管路直径之最大流速与流量表液体在管道和管道附件流动中，由于管壁的阻力而损失的扬程称为管道阻力。下表为:阀及弯管折合直管长度管路直径(mm)最大流量(L/s)最大流量(m3/h)最大流速(m/s)2513.62.04382.592.21504.17152.12656.67242.017510.00362.2610018.4662.3312530.01082.4415043.01552.4517560.02162.4920083.33002.69250133.34802.72275160.15762.71300192.06912.71345253.99142.70种类折合管路直径倍数备注全开闸阀13未畅开加倍标准弯管25逆止阀100底阀100部分堵塞加倍管路损耗参考表管路损耗参考表管径（mm）2538506575100125150175200250300流量（L/S）13.273.50.8213.0143.10.80.4455133.21.60.46297.13.30.80.238135.91.30.40.1610209.62.10.630.260.111521.66.81.30.580.270.13208.62.71.10.50.260.0725134.11.60.740.370.123019.45.92.31.050.530.180.074010.74.21.90.930.300.12506.42.91.50.480.19609.44.32.10.680.27705.82.90.930.37807.73.71.20.49909.64.71.50.61006.11.90.761107.22.30.91208.52.81.11303.31.3直管摩擦损失表（供估计用）管100m直管损失米数（以新铸管为标准，旧管加倍）1403.71.51604.92.01805.22.42003.0一定管路直径之最大流量限制管路直径（mm）最大流量（L/S）最大流速（m/s）管路直径（mm）最大流量（L/S）最大流速（m/s）2512.0412530.02.44382.51.6915043.02.45504.172.1217560.02.49656.672.0120083.32.697510.02.26250133.32.7210018.42.33300192.02.
