# Idealized steady hydraulic lift, efficiency is assumed
density = 1000 kg/m^3
gravity = 9.81 m/s^2
flow = 0.002 m^3/s in 0.001..0.005
head = 5 m in 2..15
efficiency = 0.6 "Assumed overall pump efficiency"
hydraulicPower := density * gravity * flow * head [W]
inputPower := hydraulicPower / efficiency [W]
check power budget: inputPower <= 250 W
scenario high head: head = 10 m
