Under fully turbulent flow conditions, the frictional pressure drop across a packed bed varies with the superficial velocity (V) of the fluid as
- AV⁻¹
- BV
- CV^(3/2)
- V²
Explanation
In the fully turbulent (kinetic-energy-dominated, Burke-Plummer) regime of the Ergun equation, pressure drop scales with V².
