WebApr 13, 2024 · The general formula for underwater TL is: TL = B * Log 10 (R 1 /R 2), where TL = transmission loss in dB B = transmission loss coefficient R 1 = the distance of the modeled SPL from the driven pile, and R 2 = the distance from the driven pile of the initial measurement This formula neglects loss due to scattering and absorption, which is ... WebLongitudes were specified in signs, degrees, minutes, and seconds. For example, a longitude of ♌ 19° 55′ 58″ is 19.933° east of the start of the sign Leo. Since Leo begins 120° from the vernal equinox, the longitude in modern form is 139° 55′ 58″. [9] See also: solar term
