Buckingham pi theorem
Videos
In engineering, applied mathematics, and physics, the Buckingham π theorem is a key theorem in dimensional analysis. It is a formalisation of Rayleigh's method of dimensional analysis. Loosely, the th

In fluid dynamics, the Reynolds number is a dimensionless quantity that helps predict fluid flow patterns in different situations by measuring the ratio between inertial and viscous forces. At low Rey

…dimensions to form p = n − k = 5 − 3 = 2 independent dimensionless numbers. Usually, these quantities are chosen as R e = ρ n D 2 μ , commonly named the Reynolds number which describes the fluid flow regime, and N p = P ρ n 3 D 5 , the power number, which is the dimensionless description of the stirrer. Note that the…
