This calculator computes the pressure drop across a packed bed using the Ergun equation. Ideal for chemical engineers and students dealing with fluid dynamics in packed beds.
All calculations are based on the Ergun equation, a fundamental principle in fluid dynamics for packed beds. For detailed reference, see Wikipedia - Ergun Equation. All calculations strictly follow the formulas and data from this source.
ΔP = (150 * (1 - ε) / ε^3) * (μ * v / d^2) + (1.75 * (1 - ε) / ε^3) * (ρ * v^2 / d)
Consider a packed bed with a superficial velocity of 0.1 m/s, particle diameter of 0.01 m, fluid viscosity of 0.001 Pa.s, and a bed voidage of 0.4. The pressure drop can be calculated using the Ergun equation to yield a result of approximately 200 Pa.
The Ergun equation calculates the pressure drop across a packed bed of particles.
The pressure drop is influenced by the fluid's velocity, viscosity, the particle diameter, and the voidage of the bed.
