Note ：Normal volume Calculations

1).筒体容积V1计算 Shell volume Calculations 筒体内径Di =1000mm 筒体长度H=1500mm 筒体容积V1=(Di/2)2 ×π× H=（1/2）2×3.1416×1.5=1.17 m 3 2).封头容积V2计算 Head volume Calculations 按GB/T25198-2010压力容器封头 附录A 计算

Standard basis GB/T25198-2010 Heads for pressure vessel Appendix A 封头内径Di=1000mm 封头直边高度h=25mm V2 =(π/24)D i 3+(π/4)D i 2h
