Question
Why do we invert the (y) axis in the pressure distribution plot?
Because the pressure spike is otherwise not clearly visible
Because otherwise the flow over the top side of the airfoil is at the bottom of the graph and vice versa
To visualise any adverse pressure gradient
None of the above

The correct reasoning for inverting the (y) axis in pressure distribution plots is primarily:
**Because otherwise the flow over the top side of the airfoil is at the bottom of the graph and vice versa.**
In fluid mechanics, lower pressure values are typically associated with higher velocities due to Bernoulli's principle, which occurs over the top surface of an airfoil. By inverting the y-axis, the pressure drops over the airfoil's upper surface are shown higher on the graph, making it easier to visualize the pressure distribution in relation to the airflow over the airfoil.
