Table 2. Variation of the capillary number (Ka) for different experiments on streamer formation. For all the cases, we consider μ_f ~ 10⁻³ Pa−s and γ = 0.01 N/m. Also μ_b ~ 10⁴ Pa−s¹³, so that μ_b/μ_f = 10⁷. Here we tabulate all the possible Ka corresponding to the different flow rates employed in a given experiment.
