## Fluid Forces:

Fluid forces are different kinds which are explained below, different types of forces act on fluids depends on the type of flow like open, closed, low velocity, high velocity, etc.

### Gravity force:

Gravitational Force is seen in open channel flows like Rivers, canals, etc.

### Pressure Force:

Pressure force is seen in pipe flows.

### Viscous Force:

We can observe this kind of force when there is more Viscosity.

### Turbulent Force:

When the effect of viscosity decreases turbulent force is caused.

### Compressibility Force:

When the liquids are flowing in high velocity the compressibility force acts on it.
All these forces are part of external forces acting on the fluid.

### Evler's Analysis:

Evler's analysis is a combination of gravitational and pressure force. Evler's equation depends on the motion.
The Evler's equatio is,
dp/ ρ + gdz + vdv =0

### Navier stokes equation:

The combination of Evler's analysis and viscosity force is called the Navier strokes equation.

### Reynold analysis:

The combination of the Navier stroke equation and turbulent force is called Reynold analysis.
