Process Flow Rate at 66% transfer efficiency: a worked example

This worked example runs the process flow rate numbers for a tougher week than the baseline: 66% transfer efficiency instead of the typical 92%. Estimate effective process flow rate from transferred volume, runtime, and operating efficiency.

The inputs for this scenario

  • transferred fluid volume: 12,000 gal (held at the documented default)
  • transfer runtime: 4 hr (held at the documented default)
  • transfer efficiency: 66 % (the input this scenario stresses; the baseline uses 92)

Working through the calculation

  • The calculation starts from the formula this tool documents: Raw process flow rate = transferred volume รท transfer runtime.
  • effective process flow rate works out to 1,980 gal / hr at these inputs, and this is the headline figure for the scenario.
  • raw process flow rate works out to 3,000 gal / hr at these inputs.
  • transfer efficiency works out to 66 % at these inputs.
  • transfer runtime works out to 4 hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where transfer efficiency sits at 92% and the headline result is 2,760 gal / hr, this scenario comes in 28.26% below the baseline at 1,980 gal / hr.
  • Use it when validating pump capacity, planning batch transfer windows, or comparing rated versus actual line throughput. 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

  • effective process flow rate: 1,980 gal / hr (headline result)
  • raw process flow rate: 3,000 gal / hr
  • transfer efficiency: 66 %
  • transfer runtime: 4 hr
