    Fun physics activity!!

    1. The problem statement, all variables and given/known data
    Under the conditions of normal activity an adult inhales about 1.1l of air during each inhalation. Using a stopwtch, determien the time for one of your own inhalations (avg several to get two significant digits) and hence estimate the volume flow in m^3/s through your trachea during inhalation. the diameter of adult human trachea is 25mm

    2. Relevant equations

    3. The attempt at a solution
