3、面形心处的压强pc与平面面积A的乘积：P=PcA方向垂直指向受压面。对于上下边与水面平行的矩形平面上的矩形平面上的静水总压力及其作用点的位置，可采用压力图法：静水总压力P的大小等于压强分布图的面积Ω和以宽度b所构成的压强分布体的体积。P=Ωb若压强分布图为三角形分布，如图，则P=1/2ρgH2be=1/3H式中:e-为三角形压强分布图的形心距底部的距离.HPeH3otherstaffoftheCentre.Duringthewar,ZhuwastransferredbacktoJiangxi,andDirectorofthenewOfficeinJingdezhen,JiangxiCommit
