Introduction

Flow often :

• Ideal fluid 
• No viscosity
• Incompressible 
• Not exist (to consider what will happen to an ideal fluid in a particular fluid flow problem in order to simplify the problem)

Real fluid : 

• Effects of viscosity

Type of flow :

• Incompressible fluid - energy per mass, energy per volume, energy per weight 
• Steady
• Uniform
• Path line
• Stream line
• Flowrate - volume flow rate (discharge), mass flow rate, weight flow rate

Equation :

• Continuity
• Bernoulli
• Euler
• Toricelli
