Fundamentals of Fluid Flow Flashcards
The amount of fluid passing a section of a stream in unit time
Discharge (m^3 / sec)
Discharge is also known as
Volume Flow Rate
This occurs when discharge passing a cross section is constant
Steady Flow
This occurs when the ave velocity of flow is the same at every cross section
Uniform Flow
It happens when cross sections and velocity changes during fluid flow
Non-uniform Flow
It states that the discharge at every section of the stream is the same
Continuous Flow
It is the ability of a mass to do work by virtue of its velocity
Kinetic Energy
An energy transmitted to the fluid by another mass
Pressure Energy
It is the sum of kinetic and potential energies in fluid
Total energy or head
The rate of doing work per unit of time
Power
1 horsepower is how many watts
746 watts
A theorem stating “neglecting head lost, the total amount of energy per unit weight is constant at any point
Bernoulli’s Energy Theorem
The physicist behind the “ Bernoulli Energy Theorem”
Daniel Bernoulli
It is used to raise water from lower elevation to higher elevation
Pumps
It extracts flow energy and convert it to mechanical energy
Turbines
The graphical representation of potential head
Hydraulic Grade Line
It is always above the Hydraulic Grade Line by an amount equal to the velocity head
Energy Grade Line
