1. Velocity Defect Concept
The chapter discusses the concepts of velocity defects, dimensional analysis in fluid dynamics, and the flow phenomena in pipes including pipes in series and parallel configurations. It explores the implications of energy losses within these systems and formulates equations to calculate flow characteristics based on experimental data and theoretical principles.

What we have learnt
- Velocity defects quantify how far the measured velocity deviates from the average velocity.
- Energy losses in pipes can be categorized into major and minor losses affecting fluid flow.
- The equations governing fluid flow in series and parallel pipe arrangements enable the calculation of discharge and energy losses.
Key Concepts
- -- Velocity Defect
- It measures the difference between the average velocity and the actual velocity within a fluid flow.
- -- Head Loss
- The loss of energy that occurs when a fluid flows through a pipe due to friction and changes in flow direction.
- -- DarcyWeisbach equation
- It relates the head loss due to friction in a pipe to the length, diameter, flow velocity, and a friction factor.
