WebMar 1, 2024 · The orifice Area is proportional to diameter squared, which means a ¾” orifice is significantly larger than a ¼” orifice. We can calculate the ratio between the two using simple math: Now that we know the difference in size, we simply multiply the free air CFM by that difference. In this case, we’re multiplying the free air CFM by 9. WebThe scenarios that should be considered when calculating the capacity of the vent in a storage tank are the following: Tank inbreathing due to liquid leakage/drainage (volumetric displacement, liquid transfer). Tank inbreathing due to the condensation of vapors in the space of the tank (thermal effect).
