How to Calculate Projected Area for Wind Loads Sciencing
WebDec 28, 2024 · The circle's projected diameter equals the diameter of the sphere. The projected area calculation therefore uses the area formula for a circle: area equals pi times radius times radius, or A=πr 2. If the diameter of the sphere is 20 feet, then the radius will be 20÷2=10 and the projected area will be A=π × 10 2 ≈3.14 × 100=314 square feet. WebJan 1, 2004 · Maximum Projected Area (C) in square inches is found by sectioning the core at the largest point exposed to plastic. Maximum Injection Pressure (P) is nozzle pressure in psi (hydraulic ram injection pressure x 10). Core Force (F) = P x C.
