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

 

Power
The total power required by the pump.

0.0 kW

Positive

Max Power
The maximum power that a unit of this type is available for purchase in the market.

300.0 kW

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 Power and the system computes the Number of Units and the Power. See also Pumping (by Centrifugal Pump): Modeling Calculations.

Sizing: Rating Mode

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

Costing

Equipment purchase cost is based on the total power consumed and material of construction. It is supplied by the built-in model assuming as material of construction SS316 and with a minimum costing power of 200 Watts.
