风压
wind pressure
蒲福风力等级表牛 注:13~17级风力是当风速可以仪器测定时用之。fengya风压(windp找，sure)风吹过障碍物时，在垂直于风速方向上单位面积上所受到的压力。对于障碍物来说，风压是两部分作用之和:一是迎风面的“动压强”(告，2)，二是背风侧的“吸压强”(告、”。将这两部分综合起来，可求得风压的公式: ，二合‘l+c，，’式中p为风压;P为空气密度;。为风速;c为结构系数。结构系数因障碍物形状而异，平板的C值为l，圆柱形障碍物为一0.3。上式中(l+C)plZ通常称为风速系数，主要取决于结构系数和空气密度。常用的风压系数通常不考虑结构系数的作用，即为阿2，在标准大气条件下，它等于1/16。由于空气密度是气温、气压和湿度的函数，各地的风压系数变化较大。在中国，沿海地区大致为1117，内陆为ljl6，青藏高原1118~1/26。对于迎风侧不是平面的障碍物而言，因为有复杂的流体动力因素参与，实际风压与上式算出的风压有较大出人。(李世奎)
