Buckingham pi theorem คือ

Web5 Buckingham’s pi-theorem This equation is solvable because the left m ⇥ r submatrix of A has rank r, and therefore its rows span Rr. This proves the claim above, and therefore the theorem. Practice Pipe flow. We consider the problem of determining the pressure drop of a fluid flowing through a pipe. The Buckingham π theorem provides a method for computing sets of dimensionless parameters from given variables, even if the form of the equation remains unknown. However, the choice of dimensionless parameters is not unique; Buckingham's theorem only provides a way of generating sets of … See more In engineering, applied mathematics, and physics, the Buckingham π theorem is a key theorem in dimensional analysis.
