A 375 ml bottle of liquor in the US and the Canadian maritime provinces is sometimes referred to as a pint and a 200 ml bottle is called a half-pint, harking back to the days when liquor came in US pints, fifths, quarts, and half-gallons.
Flux or Water Flux-Flux or water flux is typically expressed as volume per area per unit of time. Flux is used to express the rate at which water permeates a reverse osmosis membrane. Typical units of measurement are gallons per square foot per day (i.e. GFD or GSFD) or litres per square meter per hour (l/m2/hr). The flux of a RO membrane is directly proportional to temperature and pressure.
The rate of flow of fluid, particles, or energy through a given surface. Flux density. flux. The rate of flow of fluids, particles, or energy across a given surface or area. The presence of a field of force in a region of space, represented as a set of lines indicating the direction of the force. The density of the lines indicates the strength of the force. Lines used to represent magnetic fields in depictions of magnets, for example, follow the lines of flux of the field.
