Chapter 7

Flow in Closed Conduits

LEARNING OBJECTIVES

After reading this chapter and solving a representative sample of end-of-chapter problems, you will be able to:

  • Understand the hydraulic classification of smooth and rough pipes.
  • Apply the energy equation to solve practical problems related to flow in closed conduits.
  • Calculate water hammer pressures and critical closure times for valves.
  • Calculate flow distributions in pipe networks.
  • Analyze and design building water supply systems.

7.1 Introduction

A flow in which the fluid completely fills a conduit is classified as a flow in a closed conduit. Gases generally fill the conduit in which they are being transported. In contrast to gases, liquids only undergo closed-conduit flow when there ...
