FLUID MECHANICS 203 TUTORIAL No.2 APPLICATIONS OF …
1 FLUID MECHANICS 203 TUTORIAL APPLICATIONS OF BERNOULLI On completion of this TUTORIAL you should be able to derive Bernoulli's equation for liquids. find the pressure losses in piped systems due to FLUID friction. find the minor frictional losses in piped systems. match pumps of known characteristics to a given system. derive the basic relationship between pressure, velocity and solve problems involving flow through orifices. solve problems involving flow through Venturi meters. understand orifice meters. understand nozzle meters. understand the principles of jet pumps solve problems from past papers. Let's start by revising basics. The flow of a FLUID in a pipe depends upon two fundamental laws, the conservation of mass and energy. 2 1. PIPE FLOW The solution of pipe flow problems requires the APPLICATIONS of two principles, the law of conservation of mass (continuity equation) and the law of conservation of energy (Bernoulli s equation) CONSERVATION OF MASS When a FLUID flows at a constant rate in a pipe or duct, the mass flow rate must be the same at all points along the length.
