This video lecture delves into the concept of viscosity in fluid mechanics, focusing on the calculation of viscous force as a function of velocity profiles. The lecturer explains how, after achieving a steady state, velocity depends solely on the z-coordinate, leading to different velocity profiles and corresponding viscous forces. The formula for calculating viscous force, involving the cross-sectional area and velocity gradient, is derived, and its dependence on the coefficient of viscosity is highlighted. The unit conversion from poise to SI units is also discussed.

This video lecture explains the concept of surface tension, why it's distinct from pressure, and its role in understanding the behavior of particles at fluid surfaces. It begins by highlighting the forces experienced by particles within a fluid compared to those at the surface, leading to the necessity of defining surface tension. The lecture further explains the properties and calculation of surface tension using a U-shaped wire and a sliding rail setup. It concludes with a summary of the properties of surface forces and their distinction from pressure forces.

This lecture delves into the concept of surface forces and their behavior on different surfaces. It explains how surface forces work perpendicular to the surface periphery, aiming to minimize the cross-sectional area. The lecture also differentiates between common understanding of a surface and its physical definition, highlighting the importance of identifying surfaces with abrupt density changes. The session concludes by focusing on calculating force on single surfaces before moving on to multiple surfaces, using vector and scalar addition where appropriate.

This video explores the phenomenon of capillary rise, where a liquid rises or falls in a capillary tube due to adhesive and cohesive forces. It delves into the concepts of pressure differences across surfaces, discusses the role of the contact angle, theta C, and provides a mathematical framework to calculate the rise or fall of the liquid based on these factors.
