Process Skids, Modular Equipment & Packaged Plants worked example

Pump Package Sizing with flow rate of 250 units: a worked example

What does the result look like when flow rate reaches 250 units? The full calculation is worked below with real intermediate numbers. Use it when pump package sizing in process skids, modular equipment and packaged plants needs a few factors combined into one defensible number for process skids, modular equipment and packaged plants.

The inputs for this scenario

  • Flow rate (first duty factor): 250 units (raised for this scenario; the documented default is 100)
  • Head or pressure (second duty factor): 4 units (unchanged)
  • Unit conversion / hydraulic coefficient: 0.01 x (unchanged)
  • Process efficiency multiplier: 1 x (unchanged)

Working through the calculation

  • Applying the documented formula (Pump Package Sizing = first factor × second factor × conversion factor × process multiplier) to the inputs above produces each figure below.
  • At this operating point the engine returns 5 units for result, the number this scenario is built around.
  • At this operating point the engine returns 5 value for base product.
  • At this operating point the engine returns 1 x for multiplier.
  • At this operating point the engine returns 1,000 value for factor a x b.

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 150% above the baseline at 5 units.
  • A figure at this level is achievable when flow rate is genuinely sustained, not just peaked for a shift. It is a linear product, not a real pump-affinity or hydraulic-power calculation; it cannot capture efficiency curves, viscosity effects, or NPSH margins.

Results at a glance

  • Result: 5 units (headline result)
  • Base product: 5 value
  • Multiplier: 1 x
  • Factor A x B: 1,000 value
