Multiply the nominal product flow at 25° C by the temperature correction factor to
determine the flow at various other temperatures.
VI. Appendix
The following tables are intended as a guide to determining the flow
rates for the PWR4021 series RO systems. All flows are in gallons
per minute (GPM).
Nominal flows for systems with reject recycle and a feed water
Silt Density Index less than 3.
Nominal flows for systems with reject recycle and a feed water
Silt Density Index of 3 to less than 5.
