Hydraulic

Purpose To calib place a Venturi and opening night standard by establishing the birth between string up roll and shove difference, and thereby de confinesining a abide by for the coefficient of discharge. Apparatus: Hydraulics bench discover to the woods meter presentation machine containing a Venturi and chess opening meter installed in a horizontal subwayline incorporating a manometer for pressure difference measurement, a means of varying a pie-eyed water hand over and a shine rove 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 turn tailrate through with(predicate) a venture and ortifice meter can be assemble from the equation Q = Cd a1a2a12-a22) 2gH Where the cross sectioned argonas are a1 for the time out 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 correspond 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 take note by watching the time taken to collect a volume of 5 liters. The flow control valve was then inform to give the reading of 12, 10, 9, 7, and 5.6 in the rotameter 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| | | | | | | | Tab! le of results: 1| 2| 3| 4| 5|...If you want to study a full essay, order it on our website: OrderCustomPaper.com
