Question

If the Venturi meter was not perfectly horizontal, Do you think that it has an effect on the experiment, If, so, what adjustments should be

Answer 1

As we can see that pressure reading is not dependent on any angle so we can say that pressure reading is not change on changing the alignment from horizontal to vertical.

So there should be no effect when venturimeter is not perfectly horizontal
