注:直管道摩擦损失简易表(约计)管 100mm直管损失米数以新铸铁管为标准,旧管加倍。 一定管路直径的zui大流量值及zui大流速值
管路直径(mm) | zui大流量(L/S) | zui大流速(m/S) | 管路直径(mm) | zui大流量(L/S) | zui大流速(m/S) | 25 | 1 | 2.04 | 125 | 30.0 | 2.14 | 32 | 2.5 | 1.69 | 150 | 43.0 | 2.45 | 50 | 4.17 | 2.12 | 180 | 60.0 | 2.49 | 65 | 6.67 | 2.01 | 200 | 83.0 | 2.69 | 80 | 10.0 | 2.26 | 250 | 133.3 | 2.72 | 100 | 18.4 | 2.33 | 300 | 192.0 | 2.71 |
注:超过此值管路损失显著增加。 阀及弯管折合直管长度(每台)
名称 | 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 |
注:例如 100mm直径管,底阀折合 100倍直径等于 100χ100=10000=10m直管长度,假定流量为 8L/S查(直管道摩擦损失简易表)、只管每 100m损失1.3m、则 10m损失 0.13m、即一台 100m底阀,流量为 8L/S时,则损失扬程 0.13m。 |
