Re: What would be the effect on the results if the venturi meter was not horizontal a

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
