21. Head Losses
The chapter discusses the concepts of head loss in fluid mechanics, including both major and minor losses encountered in a pipeline system. Various equations, including the Darcy-Weisbach equation and Bernoulli's equation, are utilized to analyze pressure and discharge in pipes connecting reservoirs. Additionally, several examples illustrate common problems related to calculating head losses and discharge rates, emphasizing the significance of friction factors and loss coefficients in engineering applications.
