儲(chǔ)油罐參數(shù)的確定

1、儲(chǔ)油罐參數(shù)的確定通常加油站都有若干個(gè)儲(chǔ)存燃油的地下儲(chǔ)油罐，并且一般都有與之配套的“油位計(jì)量管理系統(tǒng)”，采用流量計(jì)和油位計(jì)來測量進(jìn)/出油量與罐內(nèi)油位高度等數(shù)據(jù)，通過預(yù)先標(biāo)定的罐容表（即罐內(nèi)油位高度與儲(chǔ)油量的對應(yīng)關(guān)系）進(jìn)行實(shí)時(shí)計(jì)算，以得到罐內(nèi)油位高度和儲(chǔ)油量的變化情況。表一二給出了小橢圓型儲(chǔ)油罐（兩端平頭的橢圓柱體，如圖所示）進(jìn)出油數(shù)據(jù)，請根據(jù)這些數(shù)據(jù)確定油罐的參數(shù)（a, b以及油罐的長度l）。 表一：進(jìn)油數(shù)據(jù)流水號油罐號累加進(jìn)油量/L油位高度/mm采集時(shí)間11150159.022010-08-18 10:32142010-08-18 10:33
