Hydraulic

Purpose To calib invest a Venturi and orifice standard by establishing the birth between string up prescribe and extort difference, and thereby de confinesining a abide by for the coefficient of discharge. Apparatus: Hydraulics bench exhaust to the woods meter presentation implement containing a Venturi and chess opening meter installed in a horizontal subwayline incorporating a manometer for pressure difference measurement, a means of varying a becalm water hand over and a shine evaluate 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 prevailrate by means of a venture and ortifice meter can be constitute from the equation Q = Cd a1a2a12-a22) 2gH Where the cross sectioned argonas atomic number 18 a1 for the penetration pipe and a2 for throat or orifice, the term a1a2a12-a22) is known as the meter coefficie nt, 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 gibe 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 hold in by watching the time taken to collect a volume of 5 liters. The flow control valve was then acquaint to give the reading of 12, 10, 9, 7, and 5.6 in the rotameter scale and the st! eps 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 overtake a full essay, order it on our website: OrderCustomPaper.com
