Flow rates under some pressure differentials were measured for the flow of water through micro-orifices. It was found that the flow rate decreases as the time has elapsed after inception of the flow under a constant pressure differential and that the decrease in flow rates is larger for city water than for pure water, and the gold orifice provides a less decrease with time in flow rates than the nickel orifice, although the flow rate at the incipient stage of the experimental run is lower in the gold orifice than in the nickel orifice.
