3 Outline • To study the: Conservation of momentum principle • Momentum transfer: the concept of balance of forces MZA@UTPChemEFluidMech Learning Outcomes At the end of the chapter, you should be able to : 1. Define continuity equation to solve steady state and unsteady state mass balance. 2. Define Bernoulli s equation. 3. Apply the energy balance to determine flow of fluid in various devices such as orifice meter, venturi MZA@UTPChemEFluidMech meter and pitot tube. 4. Apply the concept of momentum balance to determine the forces and pressure in fluid flow problems.
