In an experiment being conducted, a 5mm-diameter circular sharp-edged orifice is used in the Orifice (HM 150.09) and Jet Apparatus. The tank maintains a constant head of 42cm and collected trial#1(190ml of water within 3.9sec duration), trial#2(206ml of water within 4.2sec duration), and trial#3(168ml of water within 3.5sec duration). Measurement of the jet showed that it traveled 30cm horizontally while dropping 6.51cm. Compute the three orifice coefficients.

In a vertical pipe conveying oil of specific gravity 0.8, two pressure gauges have been installed at A and B where the diametres are 16 cm and 8 cm respectively. A is 2 metres above B. The pressure gauge readings have shown that the pressure at B is greater than A by 0.981 N/cm2. Neglecting all losses, calculate the flow rate. If the gauges at A and B are replaced by tubes filled with the same liquid and connected to a U-tube containing mercury, calculate the difference of level of mercury in the two limbs of the U-tube.Image attached.

A Venturi meter with a throat of 15 cm is used to measure the flow rate of water along a horizontal pipe that has an internal diameter of 17 cm. The flowmeter is calibrated using a solution of salt with a concentration of 10 gl–1 fed upstream of the meter at a rate of 50millilitres per second. If the pressure difference between the upstream position and the throat is found to be 759 Nm–2 A when a sample of salt-bearing water was analysed downstream from the flowmeter and found to be 15 mgl–1 , determine the flow rate of waterthrough the pipeline and the coefficient of discharge of the flowmeter.
