Wausaukee-area historical earthquake activity is significantly below Wisconsin state average. It is 96% smaller than the overall U.S. average. On 6/28/2004 at 06:10:52, a magnitude 4.2 (4.0 MB, 4.2 MW, Depth: 6.2 mi, Class: Light, Intensity: IV - V) earthquake occurred 275.0 miles away from the city center.
Heat transfer coefficient. The heat transfer coefficient or film coefficient, or film effectiveness, in thermodynamics and in mechanics is the proportionality constant between the heat flux and the thermodynamic driving force for the flow of heat (i.e., the temperature difference, Î´T): where:
Attenuation coefficients are used to quantify different media according to how strongly the transmitted ultrasound amplitude decreases as a function of frequency. The attenuation coefficient () can be used to determine total attenuation in dB in the medium using the following formula:As this equation shows, besides the medium length and attenuation coefficient, attenuation is also linearly dependent on the frequency of the incident ultrasound beam.n engineering, attenuation is usually measured in units of decibels per unit length of medium (dB/cm, dB/km, etc.) and is represented by the attenuation coefficient of the medium in question.
