Water Usage

  Imperial units Equivalent in metric:
Cycles of concentration cycles cycles
Blow-down rate gpm m3/h
Evaporation rate gpm m3/h
Drift losses gpm m3/h
TOTAL MAKE-UP WATER RATE gpm m3/h
Make-up water ratio % %

* Calculations based on ASHRAE-90.1-2010 ** Drift losses based on 0.005% of nominal water flow rate
