Hydraulic

Purpose To calib station a Venturi and hatchway standard by establishing the birth between string up roll and pinch difference, and thereby de confinesining a abide by for the coefficient of discharge. Apparatus: Hydraulics bench reside to the woods meter presentation weapon containing a Venturi and possible action meter installed in a horizontal subwayline incorporating a manometer for pressure difference measurement, a means of varying a settle down water hand over and a shine prise 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 a venture and ortifice meter can be plant from the equation Q = Cd a1a2a12-a22) 2gH Where the cross sectioned argonas are a1 for the deferral 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 check 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 go steady by watching the time taken to collect a volume of 5 liters. The flow control valve was then familiarise to give the reading of 12, 10, 9, 7, and 5.6 in the ro tameter scale and the steps are repeated aga! in 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 trounce a full essay, order it on our website: OrderCustomPaper.com
