About This Calculator

γ – Surface Tension

Interfacial tension between continuous and dispersed phases. Measured in mN/m. Lower values promote smaller droplets. Typical values: 20–100 mN/m

μd – Dispersed Viscosity

Dynamic viscosity of the dispersed phase liquid. Measured in centipoise (cP). Affects droplet formation and stability.

μc – Continuous Viscosity

Dynamic viscosity of the surrounding continuous phase. Measured in cP. Higher viscosity increases droplet size through momentum transfer resistance.

Qd – Dispersed Flow Rate

Volume flow rate of the dispersed phase in microliters per minute (μl/min). Direct impact on droplet production rate and size.

Qc – Continuous Flow Rate

Volume flow rate of the continuous phase in μl/min. Higher flow rates promote smaller droplet formation through shear forces.

Droplet Size Prediction

Calculated using two-phase flow dynamics equations accounting for interfacial tension, viscous forces, and flow rate ratios in microfluidic systems.

Note: Droplet size is calculated based on two-phase flow dynamics accounting for surface tension, viscous forces, and flow rate ratios. For precise calculations in your specific application, consult with our spray technology experts.
