1、水头计算公式位置水头H_1=h(m);压力水管H_2=P/ω=P/1000=10P_0(m);速度水头H_3=v_2/2g(m)。式中h为相对于基准平面的高度(m);P为水压(kg/m~2);P_0为水压(kg/cm~2);ω为单位体积的水重(1000kg/m~3)。
1, head calculation formula position head H_1 = h (m); pressure hose H_2 = P / ω = P / 1000 = 10P_0 (m); velocity head H_3 = v_2 / 2g (m). Where h is the height relative to the reference plane (m); P is the water pressure (kg / m ~ 2); P_0 is the water pressure (kg / cm ~ 2); ω is the water weight per unit volume 3).
