Chapter 4. Overall Mass, Energy, and Momentum Balances

4.0 Chapter Objectives

On completion of this chapter, a student should be able to:

• Perform a simple mass balance on a fluid process

• Specify a control volume for solving fluid-mechanics problems

• Derive the overall mass-balance equation

• Derive the energy balance based on thermodynamic principles

• Explain the concept of the kinetic-energy correction factor

• Use the kinetic-energy correction factor for different flow regimes and problems

• Apply the energy balance to the design of a pump

• Extend the overall energy balance to derive the overall mechanical-energy balance

• Explain how the concept of work and energy is applied to pumps and piping systems

• Calculate the energy needed to operate a pump ...
