化工原理實(shí)驗(yàn)流量計校核實(shí)驗(yàn)報告

一、試驗(yàn)操作

流量計校核生疏試驗(yàn)裝置，了解各閥門的位置及作用。對裝置中有關(guān)管道、導(dǎo)壓管、壓差計進(jìn)展排氣，使倒U形壓差計處于工作狀態(tài)。對應(yīng)每一個閥門開度，用容積法測量流量，同時登記壓差計的讀數(shù)，按由小到大的挨次5－6大流量到小流量重復(fù)一次，然后取其平均值。100mm40s。二、數(shù)據(jù)處理1.數(shù)據(jù)記錄400mm；寬300mmd〔mm：25d〔mm：15.3470查出試驗(yàn)溫度下水的物性：密度ρ=996.2542kg/m3 粘度μ=0.000958PaS2.數(shù)據(jù)處理Redu
