化工原理實驗流量計校核實驗報告

1、流量計校核、實驗操作1 .熟悉實驗裝置，了解各閥門的位置及作用。2 .對裝置中有關(guān)管道、導(dǎo)壓管、壓差計進行排氣，使倒U形壓差計處于工作狀態(tài)。3 .對應(yīng)每一個閥門開度，用容積法測量流量，同時記下壓差計的讀數(shù)，按由小到 大的順序在小流量時測量8-9個點，大流量時測量5-6個點。為保證標(biāo)定精 度，最好再從大流量到小流量重復(fù)一次，然后取其平均值。4 .測量流量時應(yīng)保證每次測量中，計量桶液位差不小于100mm£測量時間不少于 40s。、數(shù)據(jù)處理1 .數(shù)據(jù)記錄計量水箱規(guī)格：長 400mm寬300mm管徑 d (mrm : 25孔板取喉徑d0 (mrm : 15.347查出實驗溫度下水的物性：密度
