The performance characteristics of a rotodynamic machine is found
to be dependent on the ff:
The power P, transfer between rotor and fluid, the volumetric flow
rate Q, the difference of energy per unit mass across the machine
gH, the rotational speed, N the diameter of the rotor D, the
density of the fluid p, the absolute viscosity u of the fluid, the
bulk modulus K of elasticity of the fluid and the absolute
roughness ɛ of the machine's internal passages. By using the
variables N and D as part of the repeating variables, determine
the relationship between the variables.
