The formula to calculate the static pressure from CFM is:
\[ \text{Pstatic} = \text{Ptotal} - \left(\frac{\text{CFM}}{\text{A}} / 4005\right)^2 \]
Where:
Static pressure is the pressure exerted by a fluid at rest. It is an important parameter in fluid dynamics and HVAC systems.
Example:
Calculation:
\[ \text{Pstatic} = 2 - \left(\frac{1000}{2} / 4005\right)^2 = 2 - 0.0625 = 1.9875 \text{ lbf/ft²} \]
