For rotodynamic fluid machines of a given shape, and handling an incompressible fluid, the relevant variables involved are D (the rotor diameter), Q (the volume flow rate through the machine), N (the rotational speed of the machine), gH (the difference of head across the machine, i.e., energy per unit mass), p (the density of fluid), µ (the dynamic viscosity of the fluid) and P (the power transferred between fluid and rotor). Show with the helpof Buckingham's n theorem that the relationship between the variables can be expressed by a functional form of the pertinent dimensionless parameters as O (Q/N D², gH/N² D², p N D²1µ, P/p N³ D°) = 0 %3D
