Speed of sound in wind

  1. Sep 1, 2007 #1
    This isn't really a homework problem, but I am doing a research paper on the topic 'the Speed of sound in different air velocities'.

    I was just wondering is this is an appropriate topic, and whether or not I would be able to research and collect enough data for a 4000 word essay.

    Any comments, suggestions, or just anything is well appreciated.

    Also, if possible could you recommend any reading material that would help with my topic?

    Thanks.

    Do some research on the speed of sound, which is a function of the mass density of the gas through which it travels (same of liquids and solids).

    Compare typical wind velocities with the speed of sound, and consider the Doppler effect.

    One could consider the properties of the sound too

    thanks so much.

    just a question, does the doppler effect have a place in this? Since it isn't the observer who moves or the sound source, just the medium, does it affect the speed of sound?
