Due to the existence of the eddy and the abrupt bend of the stream line, the pressure on the four faces has the distribution as follow : the lowest pressure appears at several centimeters after the angle point along the top boundary, the highest pressure appears near the center line of the vertical shaft on the bottom boundary, near the angle point, the pressure on the inner boundary decreases with the decreasing height, the pressure on the external boundary decreases slightly in the right - angle region, and increases obviously near the corner
迴流漩渦的存在，以及直彎處流線的急劇彎曲，導致壁面壓力分佈在上表面距彎點一定距離后出現壓力最小值，下表面上，在豎井中心線略偏下游的位置出現壓力最大值，豎井內表面接近彎點處出現壓力沿程降低的現象，豎井外表面壓力在進入直彎后先是沿程略有降低，在直彎角落處又明顯升高。
