Butterfly Throttle Valve: Projected Opening Geometry
Calculate ideal thin-disc projected opening area and its change with angle. An entered area multiplier provides a comparison value, not valve flow or sizing.
Wing Throttle Valve: Animation and Area-Comparison Calculator
Explore a rotating wing and compare an assumed sine-based opening area, pressure-area product and uniform-gap approximation. Steam flow is not predicted.
Starting Lever Mechanism: How It Works, Parts, Diagram and Uses in Steam Engines
