A transportable system for creating an ORP in water includes an ozone supply unit and a manifold housed in separate enclosures on a wheeled frame. The ozone supply unit feeds into the manifold which contains a plurality of fluid paths and has one or more ozone intake ports. The ozone intake ports are fluidically coupled to one or more ozone output ports of the ozone supply unit. The manifold includes flow switches configured to transmit control signals to one or more controllers of the ozone supply unit in response to sensing a flow of water through the fluid paths in order to cause the ozone supply unit to generate ozone. The manifold also includes fluid mixers that are fluidically coupled to the ozone intake ports and configured to introduce the ozone generated by the ozone supply unit into the water flowing through the fluid paths.

A method of obtaining a numerical model is disclosed. The numerical model correlates estimated capillary tube output diameter values to minimum pressure for gas bubble generation (MPGBG) values. An MPGBG value of each capillary tube in the reference group is measured for a liquid. An output diameter of each of the capillary tubes is measured by a microscope apparatus. A numerical model that correlates estimated capillary tube output diameter values to MPGBG values for the liquid is calculated. A method of estimating an output diameter of a capillary tube includes the following steps. An MPGBG value of the capillary tube for a liquid is measured, and the measured MPGBG value is input into the numerical model to estimate the capillary tube output diameter value. Other methods include a method of estimating an output diameter value of a capillary tube in a test group, a method of estimating and storing output diameter values of capillary tubes in a test group, methods of selecting at least one capillary tube from a plurality of capillary tubes in a test group, and a method of cutting a capillary tube to a desired estimated capillary tube output diameter value.
