Isolated Circular Tank - Aerodynamic Shape Factor AS1170.2

Isolated Circular Tank - Aerodynamic Shape Factor AS1170.2

Isolated Circular Tank - Aerodynamic Shape Factor AS1170.2


I am working on a circular water tank that is 6m in diameter and the tank itself is 1m high. This tank is held 10m above ground on a frame. I am trying to work out the aerodynamic shape factor using AS1170.2 Cl C5.2.1. The formula for Cpb is only valid provided c/b is between 0.25 and 4.0 inclusive. in my case c/b=1/6=0.167. Which means I cannot use that formula to calculate cpb. So what do I do? The code is not very clear on this.

Any assistance is much appreciated.

You probably need to look at the paper which the code references for this and see why they put in the limits and then use engineering judgement.
