# Fan flow and power
# Scope: Incompressible fan air power with supplied total efficiency.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

flow = 0.1 m^3/s
pressure = 200 Pa
efficiency = 0.6

power := flow*pressure/efficiency [W]

check power budget: power <= 50 W

scenario alternative: flow = 0.08 m^3/s
