well im going to tell your teacher that your looking up answers you very bad kid. cha cha now.
A= actually its fluid pressure and fluid pressure is any kind of fluid(gas,liquid,air,are all fluid. Fluid Pressure is any fluid that is exerted on the surface, to calculate fluid pressure divide the force by the area over which it is applied.
The static head the distance to the point of application or the height the pump has to overcome for liquids. For air likewise is almost the same except that it is ducted, refer to Moody chart.The pressure exerted by a still liquid or gas, especially water or air.
Hydraulics
If its in a container, pressure is downward and outward due to gravity and confinement respectively. If its on a flat surface without confinement, the pressure is exerted downwards on the surface and the boundaries are held by a combination of adhesion and cohesion.
Pascal's law states that "pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid, so that the pressure ratio (initial difference) remains same."

Bernoulli's principle.
Bernoulli's principle states that as the speed of a moving fluid increases, the pressure exerted by the fluid decreases.

Drag is the force exerted by a fluid stream on any obstacle in its path or felt by an object moving through a fluid.
The Bernouli Principle states that sideward pressure exerted by a moving fluid decreases as the fluid's velocity increases.
