Cyclonic vacuum cleaner

A contemporary sketch model

Every number below is a modern illustrative assumption. The historical drawing supplies a question; the source model is an exercise in reasoning about it.

flow = 0.03 m^3/s in 0.01..0.05 "Illustrative operating airflow"
pressureDrop = 4000 Pa ± 20% "Assumed measured total system loss"
efficiency = 0.5 "Assumed fan efficiency at operating point"
shaftPower := flow*pressureDrop/efficiency [W]
check motorBudget: shaftPower <= 300 W
probe fanPower: shaftPower [W]
sweep Airflow: flow = 0.01, 0.03, 0.05 m^3/s

Model limits

Steady power budget; no cyclone separation efficiency, particle trajectories, fouling evolution or CFD. Pressure drop and efficiency may vary with flow.

Explore it with your agent

Create a Study, inspect the installed capabilities, and use this source as a starting point. Ask the agent to explain the equations and assumptions, then replace illustrative inputs with measured evidence for your own design.

This example includes a scalar sweep. Use napkin_sketch to add the model and napkin_run to inspect the sweep; the source editor’s scalar comparison view is for simple scenarios.
