# Micro-hydro power
# Scope: Net-head hydro power at supplied total efficiency.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

flow = 10 L/s
head = 5 m
density = 1000 kg/m^3
gravity = 9.81 m/s^2
efficiency = 0.6

power := density*gravity*flow*head*efficiency [W]

check power target: power >= 250 W

scenario alternative: flow = 8 L/s
