Equalizer: Equipment Tab

Variable Definitions, Ranges and Default Values

The following table shows the meaning of the variables appearing in this tab, as well as their default values and their generally acceptable range. Note that due to the manner by which the variables are used by the sizing and costing equations, the range of acceptable values may be further reduced.

Variable	Default Value	Range

◙ Surface Area The total surface are of the tank.	0.0 m²	Positive
◙ Max Surface Area The maximum surface area that a unit of this type is available for purchase in the market.	1500.0 m²	Positive
○ Tank Depth The depth of the equalizer tank.	90%	(0,100]
○ Tank Geometry The geometric shape of the equalizer tank.	Rectangular	Circular / Rectangular
○ Diameter The internal diameter of a circular shaped tank.	0.0 m	Positive
○ L/W The length over width ratio of a rectangular shaped tank.	4.0	Positive
○ Length The length of a rectangular shaped tank.	0.0 m	Positive
○ Width The width of a rectangular shaped tank.	0.0 m	Positive

Symbol Key: ○ User-specified value (always input); ● Calculated value (always output); ◙ Sometimes input, sometimes output

Sizing: Design Mode

In Calculate (Design Mode), the user specifies the Maximum Surface Area and the system computes the Number of Units and the Surface Area. the user always specifies the depth of the tank. For more information on the sizing of an equalizer tank, see Equalization: Modeling Calculations.

Sizing: Rating Mode

In User-Defined (Rating Mode), the user specifies the Number of Units and the Surface Area.

Costing

Equipment purchase cost is based on the throughput and material of construction. It is supplied by the built-in model assuming as material of construction concrete.
