Calculation of the attenuation coefficient
in copper of the conductors (skin-effect) for a narrow track case--W/ (H-t)<0.
The slope of the lines represents the ratio of attenuation coefficients
for each spectral band (Figure 4 and Figure 5).
Optimal Solution Changing with Attenuation Coefficient
611 and attenuation coefficients
of regression were between 0.
T] = average temperature v = velocity p = Pressure P = perimeter of the shaft Pr = Prandtl number W = thickness of the shaft wall x = height of interests Greek symbols a = temperature attenuation coefficient
[DELTA] = difference [epsilon] = roughness [eta] = normalized temperature rise in the fire floor due to fire [theta] = normalized temperature [lambda] = thermal conductivity [mu] = dynamic viscosity v = kinematic viscosity [?
The effective attenuation coefficient
was then estimated according to
([alpha]) of ethyl acetate at 27 [degrees]C (Expt.
x] is the one used in Eq (1) (usually the one used for air under normal pressure) and attenuation coefficient
[xi] is calculated from Eq (1).
For V101 transmitter, using Pico or [micro]30 receiver, we found the attenuation coefficient
(damping factor), [alpha], to be as below in Np/m:
Therefore, aerosol or Mie scattering dominates the total attenuation coefficient
1]) of [gamma]-rays with energy E per disintegration of the gamma emitter, [mu]a[epsilon] is the linear attenuation coefficient
in air ([cm.
However, rather essential conclusions may be drawn also on the basis of a certain group of in situ measurements: quite often the complex of data, containing the concentrations of optically significant substances (phytoplankton, coloured dissolved organic matter (CDOM) and suspended matter) as well as the incoming irradiance and diffuse attenuation coefficient
, has been collected.
