在计算容器所需的油漆、绝缘层等需要量时,或者在计算容器本身重量的时候,都要计算出容器的表面积。许多槽、罐、塔都是圆柱体形状配以标准椭圆形封头(封头高度=1/4直径)。下面的公式能够用来计算此类容器外表面总的面积: A=πDL+2.18D~2 (1) 式中:A——容器外表总面积(米~2); D——容器外径(米); L——容器的长度或高度(米); π——圆周率(3.1416)。下面的公式可以用来计算那些垂直的平封容器的表面积。这类容器一端配平封头, The surface area of ​​the container is calculated when calculating the amount of paint, insulation, etc. required for the container, or when calculating the weight of the container itself. Many tanks, tanks, and towers are cylindrical in shape with a standard oval head (head height = 1/4 diameter). The following formula can be used to calculate the total area of ​​the outer surface of such containers: A = πDL + 2.18D ~ 2 (1) Where: A - the total container surface area (m ~ 2); D - M); L - the length or height of the container (m); π - the pi (3.1416). The following formula can be used to calculate the surface area of ​​those vertical flat sealed containers. One end of this type of container with a head,
