Gain a conceptual understanding of pressure drop correlations to check and interpret results from simulators and spreadsheets.
Pressure drop (∆P) is the difference in total pressure between two points due to forces acting on a fluid flowing through a network. Correlations to calculate pressure drop may take quadratic, power law, or other forms. It may be desirable to convert a correlation from one form to another to understand the underlying phenomena. It might also be necessary to convert a correlation to match the form required by a simulation.
where ∆P is the pressure drop, Q is the fluid flowrate, a, c, and d are proportionality constants, and b is the power law exponent.
