Very interesting exploration. However does this assumption really hold for the commonly used valves: >Since temperature has a nearly >linear relationship with control >rotation I thought the valves have circular openings and the flow changes non linearly, which I have always experienced too. Just a few days back I was thinking of why no one has thought about linear controls.
