    The flux is the rate of water discharged by the hose, divided by the cross-sectional area of the hose (e.g., gal/hr in 2 or in 3 /hr in 2 = in/hr). Flux is commonly expressed on a volume basis (e.g., m 3 /m 2 s), which simplifies to a velocity unit (m/s). Flux, however, is not the distance water travels per unit time as the simplification suggests.
