I posted this question on the forum 3 years ago but did not get an answer. I finally did got the information that I needed but somehow I cannot find the calculations.
I am trying to calculate the % solid of debris netting from a permeability test performed by a manufacturer. The permeability is 4373.5 CFM/square foot. I know the answer is derived from the ASCE velocity pressure calculation qz = 0.00256 Kz*Kzt*Kd*V^2*I. I know I need to divide 0.00256 by something and then multiply by the permeability. Or something like that. I'm pretty sure the answer is the netting is 46% solid. I know the answer comes from how the qz formula is derived but I tried but I can't find the derivation. What does the 0.00256 represent? If I knew that I think I could figure it out. Any help would be greatly appreciated!
Thanks!
