Pump Package Sizing with flow rate of 50 units: a worked example

This worked example runs the pump package sizing numbers for a tougher week than the baseline: flow rate of 50 units instead of the typical 100 units. Pump Package Sizing multiplies a flow-related first factor, a head- or pressure-related second factor, a conversion factor, and a process efficiency multiplier to produce a quick sizing number for a packaged pump skid.

The inputs for this scenario

  • Flow rate (first duty factor): 50 units (the input this scenario stresses; the baseline uses 100)
  • Head or pressure (second duty factor): 4 units (held at the documented default)
  • Unit conversion / hydraulic coefficient: 0.01 x (held at the documented default)
  • Process efficiency multiplier: 1 x (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Pump Package Sizing = first factor × second factor × conversion factor × process multiplier.
  • Result works out to 1 units at these inputs, and this is the headline figure for the scenario.
  • Base product works out to 1 value at these inputs.
  • Multiplier works out to 1 x at these inputs.
  • Factor A x B works out to 200 value at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where flow rate sits at 100 units and the headline result is 2 units, this scenario comes in 50% below the baseline at 1 units.
  • Use it as an early hydraulic sizing estimate for a pump skid before detailed curve, efficiency, and NPSH analysis. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Result: 1 units (headline result)
  • Base product: 1 value
  • Multiplier: 1 x
  • Factor A x B: 200 value
