The bubble diameter increases with air flow rate, air pressure, orifice diameter and the solution depth, and decreases with the orifices number and liquid viscosity.
Comparison of two experimental methods in drop-stitch measurements of the liquid viscosity coefficient
Whenever assigning property data in a heat transfer problem, bear in mind that many properties( especially liquid viscosity) are very sensitive to temperature changes.
It solved the measurement problem that is little under-well space, high liquid viscosity and high operation temperature.
