Hydraulics Terms Reviewer

A liquid property governed by friction and heat conduction effects.

• Velocity Property

• Discharge Property

• Transport Property

• Contraction Property

Compression stress at a point in a static fluid.

• Pressure

• Stress

• Viscosity

• Density

A quantitative measure of a fluid's resistance to fluid. It determines the fluid strain rate that is generated by given applied shear stress

• Friction

• Roughness

• Discharge

• Viscosity

The energy in the substance that is stored in a system by molecular activity and molecular bonding forces.

• Internal Energy

• Specific Energy

• External Energy

• Bernoulli's Energy

Fluids that require gradually increasing shear stress to maintain a constant strain rate.

• Newtonian

• Thixotropic

• Rheopectic

• Bingham

A process when the liquid pressure is dropped below the vapor pressure due to a flow phenomenon.

• Freezing

• Cavitation

• Dilation

• Boiling

A method that computes the pressure field of the flow pattern, not the pressure changes that a particle experiences as it moves through the field

• Eulerian Method

• Lagrangian Method

• Newtonian Method

• Hardy-Cross Method

The locus of particles that have earlier passed through a prescribed point

• Streamline

• Path line

• Streak line

• Jet line

The pressure at any point in the frictionless flow where the velocity is zero. It is also the highest pressure possible in the flow if elevation changes are neglected.

• Ambient Pressure

• Absolute Pressure

• Dynamic Pressure

• Stagnation Pressure

The energy that can be converted to mechanical work completely and directly by an ideal mechanical device such as an ideal turbine

• Heat Energy

• Mechanical Energy

• Potential Energy

• Kinetic Energy
