Effectiveness Flow Ratio Modifier Curve
This curve modifies the effectiveness design value specified by multiplying the value by the result of this curve. The modifying curve is a function of flow fraction, which is the ratio of the current primary air flow rates divided by the design primary air flow rates. If this input curve is blank, the effectiveness is assumed to be constant. Any curve or table with one independent variable can be used.
Water Pump Power Modifier Curve
This curve modifies the pump electric power by multiplying the design power by the result of this curve. The normalized curve is a function of the primary air flow fraction as independent variable. The flow fraction is the ratio of the primary air during current operation divided by primary air Design Air Flow Rate. If this input field is left blank, the pump power is assumed to linear vary with the load.
