Testing Poiseulle's Law: Flow Rate vs Length

[Jodi]

Hi; Could someone please help me with this question: "Suppose you have measured the flow rate for a number of tubes with different lengths but the same radius, how would you graph your data to test Poiseulle's law (Hint: choose the scales of the axes so that the theoretical graph is a straight line)"
Could I do flow rate (change in V)/(change in time) on the y-axis and do length on the x axis? Thanks for your help.

Flow versus inverse length would give you the linear appearance required of the theoretical graph.

Daniel.
