Hi
I'm almost certain this is a dumb question, but I can't work out what I'm doing wrong. I'm currently building a pair of the Microtowers from the frugal-phile website using the Pluvia 7HD. The port for this is specified as 3 inches diameter by 4 inches length. The pipe I have for this is 80mm internal diameter. It seems unlikely that that would make much of a difference, but to check, I've tried to re-calculate the port-length using the equation Lv=(23562.5*Dv^2*Np/(Fb^2*Vb))-(k*Dv) (as recommended in the plans). When I do it though, it tells me the port should be over a metre long. Where am I going wrong?
