What is the definition of pressure in Fluid Mechanics?
Pressure is the distribution per unit area of a force normal to a surface.
Pressure is similar to shear stress, but the force is parallel to the surface.
To evaluate the pressure at a certain point in a fluid mass at rest, a small cubic fluid element submerged in that mass is considered.
a) Only statement 1 is correct.
b) Statements 1 and 2 are correct.
c) Statements 1, 2 and 3 are correct.
