1
it is the resistance of fluid to change its volume in a confined space. Usually affects the solution of practical problems in hydraulics only by changing it's unit weight.
Compressibility
2
is the ratio of the stress(change of pressure ) to the strain (change in volume divided by the original volume)
Modulus of Elasticity or Bulk Modulus of the fluid
3
is the force of molecular attraction per unit length of free surface, it is a function of both the liquid and the surface in contact with the liquid
surface tension
4
the rise or fall of a liquid in a small diameter tube inserted in to the liquid.
Capillary Effect
5
the curved free surface of a liquid in a capillary tube
Meniscus
6
the forces between like molecules such as water and water
Cohesive Forces
7
the forces between unlike molecules such as water and glass
Adhesive Forces
8
is a measure of the resistance to flow of a fluid or it may be defined as the ratio of the shearing stress or force between adjacent layers of fluid to the rate of change of velocity perpendicular to the direction of motion
Viscosity
9
defined as the absolute viscosity divided by density , it is the ratio of the dynamic viscosity of fluid to its mass density
Kinematic Viscosity
10
the force a flowing fluid exerts on a body in the flow direction, partly because of friction caused by viscosity
Drag Force
11
Fluids or which the rate of deformation is proportional to the shear stress
Newtonian Fluids
12
conservation of mass expression for steady flow open system. In the flow of mass flow rate and Volume flow rate of the fluid into or from the system

used Various techniques to convert the pressure effect to an electrical effect such as change in voltage, resistance or capacitance.
Pressure Transducer
23
work by having a diaphragm deflect between two Chambers open to the pressure inputs.
Strain Gauge Pressure Transducer
24
also called solid state pressure transducer, work on the principle that an electric potential is generated in a crystalline substance when it is subjected to mechanical pressure
