This chapter focuses on losses in pipe fittings and the application of fluid mechanics principles such as Bernoulli's equation and momentum equations. It introduces key concepts like major and minor losses, the application of Moody's charts for estimating friction factors, and various methodologies for analyzing energy dissipation in pipe systems. Understanding these concepts is critical for the design and efficiency of water supply systems.

Term: Reynolds Number
Definition: A dimensionless number that helps predict flow patterns in different fluid flow situations, determining whether flow is laminar or turbulent.
Term: Major Losses
Definition: Energy losses in pipes caused primarily by friction due to fluid viscosity.
Term: Minor Losses
Definition: Energy losses due to fittings, bends, valves, or other changes in the pipe system that disrupt flow.
Term: Moody's Chart
Definition: A graphical representation used to determine the friction factor for fluid flow in pipes based on Reynolds number and relative roughness.
Term: Bernoulli’s Equation
Definition: A principle that describes the conservation of energy in fluid flow, which relates pressure, velocity, and height.
