Kierrosnopeuden
Kierrosnopeus (genitive: kierrosnopeuden) is the Finnish term for rotational speed or rate of rotation, describing how many revolutions an object makes around an axis per unit time. It is commonly expressed in revolutions per minute (rpm) or in hertz (Hz), where 1 Hz = 1 rotation per second and 1 rpm = 1/60 Hz. Angular velocity is related to rotational speed by ω = 2πf, where ω is in radians per second and f is frequency in hertz.
Kierrosnopeuden is a fundamental parameter in mechanics, impacting torque, power, and dynamic behavior of rotating machinery.
Measurement of kierrosnopeuden is typically performed with tachometers, stroboscopes, optical encoders, or Hall-effect sensors, depending on
Typical applications where kierrosnopeuden is critical include internal combustion engines (rpm ranges from idling to redline),
