Final answer:
The diagram by Vitruvius that shows the winds and their effect on city layout is known as the Diagram of the winds. By creating a diagram with arrows indicating predicted air flow and testing with tissue paper at various points, students can verify and adjust their model to accurately represent air movement.
Step-by-step explanation:
The diagram called that shows the winds and their effect on the layout of the city, by Vitruvius, is known as the Diagram of the winds. When you are assigned a specific window or door to study air flow, you should start by drafting a preliminary hypothesis on a diagram about how the air will flow when that opening is utilized. This involves drawing arrows to depict the anticipated direction of the air currents. It's recommended to use pencil for this initial diagram, as adjustments may be necessary after testing.
To verify the airflow hypothesis in your room, mark four locations on the diagram where you intend to test the air. Use a strip of single ply tissue paper and note how it reacts to the airflow at these points, documenting the direction in which the paper moves. If the paper moves according to the predictions of your air flow diagram, your initial model is likely accurate.
After testing, you should modify the diagram to accurately reflect the observed air flow. This approach helps create a model that can be used to understand room ventilation and potentially predict how air would move with a new window or door added. A new diagram with this hypothetical change can serve as a tool to predict room airflow, showcasing the practical application of the model based on experimental evidence.
