1、 . 1,关于内表面积我来补充一句,就是当短半轴长度为长半轴一半时,不含直边时,椭圆封头的内表面积和体积近似计算公式为:1):内表面积=1.084(2长半轴)22):体积1.047长半轴32,椭圆形封头的内表面积和容积数据表:椭圆形封头的内表面积和容积公称直径Dg曲面高度h1直边高度h2内表面积F(m2)容积V(m3)300(350)75250.1210.005388250.160.00802400100250.2040.0115400.2230.0134450112250.2540.0158400.2750.0183500125250.3090.0213400.3330.0242500.34
