    en.wikipedia.org/wiki/Multiphase_flow

    Flow patterns in pipes are governed by the diameter of the pipe, the physical properties of the fluids and their flow rates. As velocity and gas-liquid ratio is increased, "bubble flow" transitions into "mist flow". At high liquid-gas ratios, liquid forms the continuous phase and at low values it forms the disperse phase.

    The supermoon of 14 November 2016 was 356,511 km (221,526 mi) away [1] from the center of Earth. Supermoons occur 3–4 times per year. [2] As the Earth revolves around the Sun, approximate axial parallelism of the Moon's orbital plane (tilted five degrees to the Earth's orbital plane) results in the revolution of the lunar nodes relative to the Earth.
