pyudv.attenuation.direct_models.alpha_w#

alpha_w(f, T)[source]#

Calculate the fresh water attenuation in m-1.

Parameters:

  • f (scalar, array) – Sound frequency in Hertz.

  • T (scalar, array) – Temperature in Celsius degrees.

Returns:

return the fresh water attenuation in m-1.

Return type:

scalar, array

Examples

>>> f = 2e6
>>> T = 25
>>> print(alpha_w(f, T))
