Static Pressure Power with connected fan motor load of 9.25 kW: a worked example

Suppose connected fan motor load falls to 9.25 kW. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate operating energy cost for a fan or blower from connected motor load, runtime, electricity price, and fan count or test count.

The inputs for this scenario

  • Connected fan motor load: 9.25 kW (the input this scenario stresses; the baseline uses 18.5)
  • Fan operating runtime: 8 hr (held at the documented default)
  • Blended electricity price: 0.13 $ / kWh (held at the documented default)
  • Fans or test units covered: 6 fans (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Fan energy cost = connected fan motor load × fan operating runtime × blended electricity price.
  • Fan energy cost works out to 9.62 $ at these inputs, and this is the headline figure for the scenario.
  • Energy used works out to 74 kWh at these inputs.
  • Cost per piece works out to 1.6 $ / piece at these inputs.
  • Hourly cost works out to 1.2 $ / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where connected fan motor load sits at 18.5 kW and the headline result is 19.24 $, this scenario comes in 50% below the baseline at 9.62 $.
  • It computes total fan energy cost from motor load, runtime, and electricity price, then divides by the number of fans to give a per-fan cost. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
