Hi , I am in the process of designing the orifice meter line, I have a problem to calculate the pipe line with the iso5167 standard, please help me .

What is the need of connecting the manometers to a common manifold with an air valve
instead of keeping the manometers open to the atmosphere??

[@StudyTips4U]

If pressure in a pipe is too high if manometers are open then the flow may overflow. When students do experiments and if they open an inflow valve very fast the pressure rises quickly and manometers are overflowing and may even burst.

[@nurfatinkarmila9630]

Hi ! Is there a procedure list for this experiment ? I couldn't catch all the steps in a proper steps. Hope you can help ! Thank you

[@StudyTips4U]

There are two parts of this experiment:
Part 1 Variation of the piezometric, total and velocity heads along the venturi meter
Adjust the flow rate to achieve the maximum (h1 - hT) available (therefore maximum flow rate), i.e. with h1 close to the top of its scale and hT near the bottom (h1 piezometric head at tube 1, hT piezometric head at the throat). This is achieved by manipulating both bench (inlet) and control (discharge) valves. (If difficulty is experienced the air (bleed) valve may also be adjusted). Determine the rate of flow using the tank and recording volume on the ruler installed on the bench and time. For Part 1 test, readings from all the manometer tubes should be recorded.
Part 2 Calibration of Venturi meter through measurements of Q and (Δh=h1 - hT).
Repeat the process described in Part 1 for five more flow rates. For this set of experiments, measurement of flow rate and readings from the piezometers for h1 and hT only should be recorded. The calibration factor C will later be determined from these measurements. The dimensions of the meter for each piezometer taping are shown on the Venturi meter itself.

Maam actually i performed this practical today and opened the inlet and outlet valve simultaneously but the water in manometer tube D was going down and not in E. Meanwhile water was going out from air valve too..why was this so? Can u help plz

[@StudyTips4U]

If water was going out from the air valve it is very likely that you opened inlet valve much faster than the outlet valve, I.e. it is likely that inflow was greater than outflow and pressure within the pipe increased and water was flowing through the air valve. You have to open inlet and outlet valves simultaneously but you need to do it slowly that in you can control both inflow and outflow.

@@StudyTips4U and maam why was not the level in manometer tube 5 going down. The level in tube 4 was low as compared to 5 and i tried to adjust it for 10-15mins but still it wasn't working..Can u plz highlight my mistake in this case..Moreover apparatus and parts are completely similar...
