The formula uses Kst, Filter Volume & Pred to calculate a pressure developed. This is applied to the number of vents in a system. The idea being to find a weight in Kg/m2 that a deflagration panel may have before the size must be compensated. Without detailed knowledge of the background of the equation I cannot confirm my hunch that there is a… Show more

Hi Mitchel, Thank you for your answer. I had not considered that the rotational velocity was the important factor. It makes sense that if the rotational velocity is constant and the panel is assumed to be square that a new panel of half the area has a longer radius and the torque needed to move it at the velocity will decrease. Thanks …
