管路流量計試驗

Abstract

中文摘要 藉由管路系統中流量的裝置如孔口計、文氏計、羅托計等，量測管徑所產生壓力差，再由此壓力差來計算流量，再利用管徑的壓差討論各管路損失的情形。 開始先開啟水閥，並打開流水閥使管路滿管，等水流穩定後測其流量，調整流量使其產生壓差並記錄數據及流量，最後將實驗數據繪成圖表。利用柏努力方程式及壓差，可得知實驗中各管路流量計之損失。

Abstract The pressure difference generated by measuring the pipe diameter is measured by the flow devices in the pipeline system, such as orifice meter, Venturi meter and Roto meter, and then the flow is calculated by the pressure difference, and the loss of each pipeline is discussed by using the pressure difference of the pipe diameter. First, open the water valve, and then open the water valve to make the pipeline full. After the water flow is stable, measure its flow, adjust the flow to make it produce pressure difference, and record the data and flow. Finally, draw the experimental data into a chart. The loss of each pipeline flowmeter in the experiment can be obtained by using Bernoulli equation and pressure difference.
