应用立式罐罐壁平均温度计算式的建议

The Average Tank-shell Temperature Formula Can Acurrately Measure the Tank Volume for Vertical Tank

在立式罐容量计量中,当罐壁平均温度有别于20℃时,罐容量就会发生变化。对于这个变化量的计算目前虽有多种计算方法,但计算结果的偏差是比较明显的。为此分析了各计算式的适用条件,提出应依据现有的实测数据来比较它们的计算误差,以确定适用性范围,提出了应用罐壁平均温度计算式的建议。

The tank volume will change when the average temperature of tank-shell is not at 20℃ in the measurement of vertical tank. Although there are many ways to calculate the change at present, the calculation deviation is evident. This paper analyzes the applicable conditions of various formulae, and points out that the deviation comparison should be done between the formulae in accordance with actual site data so as to determine the applicable scope for them. In the paper,the average tank-shell temperature formula is recommanded.
