At low velocities (laminar flow), the volume flow q through a small-bore tube is a function only of the tube radius r, the fluid viscosity p, and the pressure drop per unit tube length dp/dx. 2.1 show that there are only 3 fundamental dimensions for this problem and only 1 dimensionless group. 2.2 use the buckingham-pi method to obtain the dimensionless parameters. 2.3 show that the dimensionless group formed is indeed dimensionless. discuss how dimensional analysis can assist to reduce the number of experiments needed to run in order to characterize a physical phenomenon.

An electrons position cannot be known precisely only it's probability of being in a certain location can be known
