In microeconomics, a production–possibility frontier (PPF), production possibility curve (PPC), or production possibility boundary (PPB) is a graphical representation showing all the possible options of output for two that can be produced using all factors of production, where the given resources are fully and efficiently utilized per unit time.
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 ...
In fluid mechanics, the pressure-gradient force is the force that results when there is a difference in pressure across a surface. In general, a pressure is a force per unit area across a surface. A difference in pressure across a surface then implies a difference in force, which can result in an acceleration according to Newton's second law of ...
The pressure on a pressure-temperature diagram (such as the water phase diagram shown above) is the partial pressure of the substance in question. A phase diagram in physical chemistry , engineering , mineralogy , and materials science is a type of chart used to show conditions (pressure, temperature, etc.) at which thermodynamically distinct ...
An example of a geostrophic flow in the Northern Hemisphere. A northern-hemisphere gyre in geostrophic balance; paler water is less dense than dark water, but more dense than air; the outwards pressure gradient is balanced by the 90 degrees-right-of-flow coriolis force The structure will eventually dissipate due to friction and mixing of water properties.
Pressure in water and air. Pascal's law applies for fluids. Pascal's principle is defined as: A change in pressure at any point in an enclosed incompressible fluid at rest is transmitted equally and undiminished to all points in all directions throughout the fluid, and the force due to the pressure acts at right angles to the enclosing walls.
Productive capacity has a lot in common with a production possibility frontier (PPF) that is an answer to the question what the maximum production capacity of a certain economy is which means using as many economy’s resources to make the output as possible. In a standard PPF graph, two types of goods’ quantities are set.
Water potential is the potential energy of water per unit volume relative to pure water in reference conditions. Water potential quantifies the tendency of water to move from one area to another due to osmosis, gravity, mechanical pressure and matrix effects such as capillary action (which is caused by surface tension).
