In the context of a PPF, opportunity cost is directly related to the shape of the curve (see below). If the shape of the PPF curve is a straight-line, the opportunity cost is constant as the production of different goods is changing. But, opportunity cost usually will vary depending on the start and end points.
The production possibilities frontier (PPF) for guns versus butter. Points like X that are outside the PPF are impossible to achieve. Points such as B, C, and D illustrate the trade-off between guns and butter: at these levels of production, producing more of one requires producing less of the other. Points located along the PPF curve represent ...
A diagram showing the production possibilities frontier (PPF) curve for "manufacturing" and "agriculture". Point "A" lies below the curve, denoting underutilized production capacity. Points "B", "C", and "D" lie on the curve, denoting efficient utilization of production.
Showing wall boundary condition. The most common boundary that comes upon in confined fluid flow problems is the wall of the conduit. The appropriate requirement is called the no-slip boundary condition, wherein the normal component of velocity is fixed at zero, and the tangential component is set equal to the velocity of the wall.

With a constant pressure, the voltage needed to cause an arc reduced as the gap size was reduced but only to a point. As the gap was reduced further, the voltage required to cause an arc began to rise and again exceeded its original value. For a given gas, the voltage is a function only of the product of the pressure and gap length.
The fluid exerts a constant pressure on the surface once it has separated instead of a continually increasing pressure if still attached. [4] In aerodynamics, flow separation results in reduced lift and increased pressure drag, caused by the pressure differential between the front and rear surfaces of the object. It causes buffeting of aircraft ...
It's why fewer people have been to Titanic ocean depths than have been to space. Anyone who has dove to the bottom of a pool has noticed the difference in water pressure, a heaviness in the nose ...
This pressure distribution is simply the pressure at all points around an airfoil. Typically, graphs of these distributions are drawn so that negative numbers are higher on the graph, as the C p {\displaystyle C_{p}} for the upper surface of the airfoil will usually be farther below zero and will hence be the top line on the graph.
