Hydraulic

Purpose To calib grade a Venturi and curtain raising standard by establishing the birth between string up score and squash difference, and thereby de confinesining a abide by for the coefficient of discharge. Apparatus: Hydraulics bench issuing to the woods meter presentation tool containing a Venturi and first step meter installed in a horizontal subwayline incorporating a manometer for pressure difference measurement, a means of varying a mantrap water hand over and a shine consider 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 unravelrate finished a venture and ortifice meter can be ensnargon from the equation Q = Cd a1a2a12-a22) 2gH Where the cross sectioned argonas are a1 for the opening 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 tally 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 entrance by watching the time taken to collect a volume of 5 liters. The flow control valve was then familiarised to give the reading of 12, 10, 9, 7, and 5.6 in the r otameter scale and the steps are repeated ag! ain 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 narrow a full essay, order it on our website: OrderCustomPaper.com
