(adsbygoogle = window.adsbygoogle || []).push({}); 1.The motors driving the fans of a large cooling tower must be represented in a dynamic

simulation of a power plant auxiliary system.

Each fan can be described as follows:

Fan diameter = 4.5 meter

No of blades/fan = 6

Fan RPM = 90

The fan blades have a tapering cross section.

The fan cross section may be taken to taper linearly from root to tip.

The mass-per-length of each blade may be taken to vary from 8 Kg/m at the root to 3Kg/m

at the tip.

The root diameter of the fan disc is 1m.

The tip diameter of the fan disc is 4.5m.

Estimate the polar moment of inertia of the fan in Kg-m^2
