Fluid mechanics is the branch of physics that deals with the study of fluids (liquids and gases) and the forces that act on them. It involves the analysis of how fluids behave under different conditions, such as when they are in motion or at rest.
Net force in fluid mechanics refers to the sum of all the forces acting on a fluid in a particular direction. It is calculated by taking into account all the external and internal forces that act on the fluid, such as pressure, gravity, and viscous forces.
The net force on a fluid can be calculated using the fundamental laws of fluid mechanics, namely the continuity equation, Bernoulli's equation, and the Navier-Stokes equations. These equations take into account factors such as fluid density, velocity, and pressure to determine the net force acting on the fluid.
The point of action in fluid mechanics refers to the location where a force is applied on a fluid. This point is important in determining the effect of the force on the fluid, as it can influence factors such as fluid flow and pressure distribution.
The point of action can be calculated by using the principle of moments, which states that the moment of a force about a point is equal to the product of the force and the perpendicular distance from the point to the line of action of the force. By considering all the forces acting on a fluid and their respective moments, the point of action can be determined.
