What would be the effect on the results if the venturi meter was not horizontal and why?

This is research i must complete before I carryout my experiment and lab report??

Help Plz

not horizontal ---> there is a change in the specific gravitational potential energy of the fluid passing through the venturi meter and the total specific energy of the fluid is constant (assuming no headloss and no energy added)--> specific kinetic energy of the fluid must change ---> speed of the fluid changes


$$\Delta z\Rightarrow\Delta gz\Rightarrow\overline{e}=\Delta gz+ke+\overline{w_{f}}\Rightarrow\Delta ke \Rightarrow\Delta ke=\frac{v^{2}}{2}\Rightarrow\Delta v$$

overbar means constant
$$w_{f}$$ is flow work which is constant due to no headloss

The orientation of the venturi meter can have a significant effect on the results obtained. If the venturi meter is not horizontal, it can introduce errors in the measurement of the fluid flow. This is because the venturi meter relies on the difference in pressure between the throat and the inlet to determine the flow rate. If the meter is not horizontal, the fluid flow may be affected by gravity and cause uneven pressure distribution, leading to inaccurate readings.

Additionally, a non-horizontal venturi meter can also cause issues with the calibration and accuracy of the instrument. The calibration of the meter is typically done in a horizontal position, and any deviation from this orientation can result in discrepancies in the readings.

Therefore, it is essential to ensure that the venturi meter is installed and operated in a horizontal position to obtain accurate and reliable results. Any deviation from this position should be noted and considered during data analysis. It is also crucial to follow the manufacturer's guidelines and instructions for proper installation and operation of the venturi meter to minimize errors and ensure accurate results.
