# attenuationWater

Calculate ultrasound attenuation in distilled water

## Syntax

    att = attenuationWater(f, T)

## Description

`attenuationWater` calculates the ultrasonic absorption in distilled water at a given temperature and frequency using a 7th order polynomial fitted to the data given by Pinkerton (1949, The Absorption of Ultrasonic Waves in Liquids and its Relation to Molecular Constitution, Proceedings of the Physical Society. Section B, 2, 129-141).

## Inputs

`f` | array of frequency values [MHz]
`T` | water temperature [degC]

## Outputs

`att` | attenuation [dB/cm]
