Plot the pressure coefficient distribution (y-axis) versus chord location (x-axis) about the airfoil shape for each Mach Number. Reverse the orientation of the y-axis (negative numbers above the x-axis) such that the curve representing the upper surface distribution is on top and the curve representing the lower surface distribution is on the bottom.

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
