Hydraulic

Purpose To calib charge per unit a Venturi and opening standard by establishing the birth between string up invest and force difference, and thereby de confinesining a abide by for the coefficient of discharge. Apparatus: Hydraulics bench train to the woods meter presentation setup containing a Venturi and initiative meter installed in a horizontal subwayline incorporating a manometer for pressure difference measurement, a means of varying a knockout water hand over and a shine pace measuring device. Venturi meter: niche pipe diameter, d1 = 29mm. Throat diameter, d2 = 17mm. Orifice meter: Inlet pipe diameter, d1 = 29mm. Orifice diameter, d2 = 20mm. Theory: the feed inrate by dint of a venture and ortifice meter can be build from the equation Q = Cd a1a2a12-a22) 2gH Where the cross sectioned argonas argon a1 for the gate pipe and a2 for throat or orifice, the term a1a2a12-a22) is known as the meter coefficient, K i.e Q = Cd K 2gH Procedure: The apparatus was first placed entirely horizontal. channelise bubbles present in the pipe was checked and cleared out. come up the rotameter harmonize to the one described in the manual. The rotameter scale was caboodle to 12 in the beginning of the experiment.

On gaining the reading from the manometer the flow rate is calculated by applying the given equation the flow rate was also calculated with the aid of a stop regard by watching the time taken to collect a volume of 5 liters. The flow control valve was then familiarize to give the reading of 12, 10, 9, 7, and 5.6 in the rotamete r scale and the steps are repeated again to ! calculate the height difference and the flow rate respectively Observations: Rota meter(l/min)| H1(cm)| H2(cm)| H6(cm)| H7(cm)| Volume(m3/s) 10-3| Time(s)| 12| 37| 33| 43| 16.5| 5| 29.5| 10| 20.1| 17.7| 22.8| 13.6| 5| 36| 9| 11| 9| 13| 11.6| 5| 40| 7| 7.8| 6.8| 9.7| 8.6| 5| 52| 5.6| 6.5| 5.8| 8| 7.1| 5| 61| | | | | | | | Table of results: 1| 2| 3| 4| 5|...If you want to ready a full essay, order it on our website: OrderCustomPaper.com
