# Pump affinity-law scaling
# Scope: Speed affinity at unchanged impeller and fluid; similarity assumed.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

speedRatio = 1.2
flow = 10 L/min
head = 10 m
power = 100 W

newFlow := flow*speedRatio [L/min]
newHead := head*speedRatio^2 [m]
newPower := power*speedRatio^3 [W]

check motor power budget: newPower <= 200 W

scenario alternative: speedRatio = 0.96
