Batch Mixing Time at 23% viscosity, sampling, and hold allowance: a worked example
This scenario runs the batch mixing time calculation on the strong side: 23% viscosity, sampling, and hold allowance, with every other input held at its documented default. estimating blend time for a chemical batch before release sampling or transfer
The inputs for this scenario
- Batch size to mix: 2,500 gal (unchanged)
- Proven blend/turnover rate: 55 gal / min (unchanged)
- Viscosity, sampling, and hold allowance: 23 % (raised for this scenario; the documented default is 20)
Working through the calculation
- Applying the documented formula (Base mixing time = batch size to mix รท proven mixing rate) to the inputs above produces each figure below.
- At this operating point the engine returns 55.91 min for required batch mixing time, the number this scenario is built around.
- At this operating point the engine returns 45.45 min for base mixing time.
- At this operating point the engine returns 23 % for mixing allowance applied.
- At this operating point the engine returns 55 pieces / min for proven mixing rate.
How this compares with the baseline
- Against the tool's baseline example, where viscosity, sampling, and hold allowance sits at 20% and the headline result is 54.55 min, this scenario comes in 2.5% above the baseline at 55.91 min.
- Use it when setting an agitation hold time, validating a mixing step, or scheduling how long a vessel is tied up blending before the next operation. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
