13. The power required by an agitator in a tank is a function of the following four variables; (a) Diameter of impeller.
(b) Number of rotations of impeller per unit time.
(c) Viscosity of liquid.
(d) Density of liquid.
14. The Force F exerted on a body immersed in a flowing fluid is dependent on the relative velocity between the solid and the fluid u, the fluid density and the fluid Viscosity and length of body L.
The relationship between these variable may be written as:
F = K ua b c Ld
Where K = Dimensionless Constant.
From the above relationship prove that F = K L2 u2 ( NRe)-c
