In engineering, it means how much error is acceptable. Not sure what Guest User meant.

I believe Guest User is asking how close your experimental answer is to the 'correct' or book answer, as given by Bernoulli's equation.

Hope this helps!

Cheers,

I have a slightly different interpretation. It seems that we have not been given full context.

As I reconstruct things, there is some primary experiment or measurement that the student is doing. The student is asked to do a secondary measurement of air density to verify the accuracy of the primary experiment.

Possibly the primary experiment is to weigh some air and the secondary measurement of air density is a sanity check. Possibly the primary experiment is something else that could be affected by wind resistance, atmospheric buoyancy or some such and the secondary measurement of density will quantify the expected error from that source.

Thank you for your replies @haruspex, @Tom.G, and @jbriggs444! That all helps a lot!

Many thanks!
