Types of Forces Present in a Moving Liquid – The important forces present in a moving liquid are Inertia Force, Viscous Force, Gravity Force, Surface Tension Force, Pressure Force and Elastic Force.

** (a) Inertia force:** It is the product of mass and acceleration of the flowing liquid.

** (b) Viscous force:** It is the product of shear stress due to viscosity and the cross-sectional area of flow.

** (c) Gravity force:** It is the product of mass and acceleration due to gravity of a flowing liquid.

** (d) Surface tension force:** It is the product of surface tension per unit length and length of the surface of flowing liquid.

** (e) Pressure force:** It is the product of intensity of pressure and the area of a flowing liquid.

** (f) Elastic force:** It is the product of elastic stress and the area of a flowing liquid.
