Help with a Thesis

  1. Apr 8, 2013 #1
    I all, new to this forum and just looking for a bit of help in my final year thesis.
    I have built a model chimney and using a gas torch to represent a fire. I would like to know is there any way i would be able to get the flow rate of the air going through the model flue (alimumin duct). It is one meter in lenght . Thanks

    diar1000, Welcome to Physics Forums!

    When I was young my family lived in a home with a fireplace in the living room. Before lighting the fire, my father crumpled up a few newspaper sheets and jammed them up in the chimney flue. We first lighted that paper to start the updraft, then the main fire materials. As a result, our living room never filled with smoke.
