power curve

Power curve may refer to:

• The power band of an internal combustion engine, the range of speeds in which it operates efficiently
• The power curve in aerodynamics, a characteristic curve of drag vs. airspeed for airfoils
• A power law graph in statistics
• Curves used for crossfading between multiple audio signals, used in audio mixing and digital signal processing
• The relationship between statistical power and effect size (or sometimes, between statistical power and sample size).
• The power curve in geometry, the curve with trilinear coordinates (a^t:b^t:c^t) for a given power t.
