The surface tension of water provides the necessary wall tension for the formation of bubbles with water. Latent heat and gravitational potential. Example … Surface tension has the dimension of force per unit length, or of energy per unit area. Thus, the surface shape is determined by only one parameter, the over pressure of the fluid, Δp * and the scale of the surface is given by the capillary length. Surface tension (γ LV) is defined as the force which is responsible for reducing the free liquid’s surface area; the unit of this force is N m −1 or J m −2. The phenomena of rise or fall of a liquid level in a capillary tube is called capillarity or capillary action. Based on the solution of a point force acting on a substrate with surface tension, we derive the singular integral equation of this problem. If … Note- g= acceleration due to gravity and it's dimension is [LT^-2] The denominator 2 has no dimension .
