企业自备的贮油设施,一般为卧式倾斜安装贮油罐,根据企业管理考核需要,需 对油罐在
不同液面高度时的贮油量进行精确计量,以便进行油品盘点、成本考核及节油指 标考核兑现。
现对卧式倾斜安装圆柱体油罐在不同液面高度时贮油量进行计算。
图1倾斜安装油罐液面示意图
1计算公式
倾斜安装油罐及液面剖示如图1所示。
为使计算公式推导方便,将圆柱体油罐经旋转后放
入坐标系进行分析计算,如图2所示。
设油罐倾斜度为K ,即K = BC?A B;油罐底圆半径
为R ,则有底圆方程:R 2= x 2+ y 2。任一液面AC (见图2)
离底圆圆心距离为L : (L根据x轴的方向取正值或负值)。在被积区域内取被积 △ A B C,使其
