Best ResponseYou've already chosen the best response.0I assume you mean the cone shaped filters that fit inside each other drag force has th following equation: \[F _{d} = \frac{ 1 }{ 2 } \rho u ^{2} A \times C _{d}\] Now  the coefficient of drag and the Area or essentially dependent on the shap of the object as presented to the air you can see that the stack remains essentially the same shape however many filters are stacked dw:1444080697669:dw so  looking at the formula  if you approximate A and Cd are the SAME for all stack  what can you say about the Fd?
