海曾威廉公式

海曾威廉公式, h=(10.67 Q^1.852L)/(C^1.852 D^4.87)式中:Q——流量,m^3/s;L——管長,m;D——內徑,m;C——管材粗糙係數(海曾-威廉係數),塑膠管C=150,新鑄鐵管C=130,混凝土管C=120,舊鑄鐵管和舊鋼管C=100。

基本介紹

  • 中文名:海曾威廉公式
  • 表達式: h=(10.67 Q^1.852L)/(C^1.852 D^4.87)
  • 所屬學科:物理
  • 參數數據:節點,管道參數
給水管網平差,參數數據,

給水管網平差

1.平差基本數據
1、平差類型:反算水源壓力。
I=λ*V^2/(2.0*g*D)
1.0/λ^0.5=-2.0*lg[k/(3.7*D)+2.5/(Re*λ^0.5)]
Re=V*D/ν
計算溫度:10 ,ν=0.000001
3、局部損失係數:1.20
4、水源點水泵參數:
水源點水泵楊程單位(m),水源點水泵流量單位:(立方米/小時)
水源節點編號 流量1 揚程1 流量2 揚程2 流量3 揚程3
