Unmixed Water Flows for REU-2532 Series
The chart below can be used to determine water flow rates in “gallons per minute” at a given
temperature rise. In order to figure flow rates, you need the following information; requested water
temperature and inlet water temperature. Next, subtract the inlet water temperature from the requested
temperature to get your delta T or temperature rise. Then, locate your temperature rise at the bottom of
the chart. Follow that line vertically until it intersects with the flow rate line to the left. This indicates
the flow rate at your temperature rise.
