Density of Fluid by Ergun Solution

STEP 0: Pre-Calculation Summary

Formula Used

Density = (Reynolds Number(pb)*Absolute Viscosity*(1-Void Fraction))/(Diameter(eff)*Superficial Velocity)
ρ = (Re_pb*μ*(1-∈))/(D_eff*U_b)
This formula uses 6 Variables

Variables Used

Density - (Measured in Kilogram per Cubic Meter) - The Density of a material shows the denseness of that material in a specific given area. This is taken as mass per unit volume of a given object.
Reynolds Number(pb) - Reynolds number(pb) is the ratio of inertial forces to viscous forces within a fluid which is subjected to relative internal movement due to different fluid velocities.
Absolute Viscosity - (Measured in Pascal Second) - Absolute Viscosity is the measurement of the fluid's internal resistance to flow.
Void Fraction - Void Fraction is the fraction of the channel volume that is occupied by the gas phase.
Diameter(eff) - (Measured in Meter) - Diameter(eff) is a chord that runs through the center point of the circle.
Superficial Velocity - (Measured in Meter per Second) - Superficial Velocity is the volumetric flow rate divided by a cross sectional area.

STEP 1: Convert Input(s) to Base Unit

Reynolds Number(pb): 200 --> No Conversion Required
Absolute Viscosity: 24.925 Pascal Second --> 24.925 Pascal Second No Conversion Required
Void Fraction: 0.75 --> No Conversion Required

Superficial Velocity: 0.05 Meter per Second --> 0.05 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

ρ = (Re_pb*μ*(1-∈))/(D_eff*U_b) --> (200*24.925*(1-0.75))/(24.99*0.05)

Evaluating ... ...

ρ = 997.398959583834

STEP 3: Convert Result to Output's Unit

997.398959583834 Kilogram per Cubic Meter --> No Conversion Required

FINAL ANSWER

997.398959583834 ≈ 997.399 Kilogram per Cubic Meter <-- Density

What is internal flow?

Internal flow is a flow for which the fluid is confined by a surface. Hence the boundary layer is unable to develop without eventually being constrained. The internal flow configuration represents a convenient geometry for heating and cooling fluids used in chemical processing, environmental control, and energy conversion technologies. An example includes flow in a pipe.
