Principle of FLuid Machinery Flashcards
Liquids and gases together called __–
fluids
The _________ convert the potential energy or kinetic energy or pressure energy or thermal
energy or internal energy of fluid into mechanical work and are called engines or turbines or prime
movers or driving machine
fluid machines
Is an equipment capable of handling fluid, either moving the fluid or moved by the fluid.
fluid machinery
Fluid machinery is an energy in the form of the potential, kinetic and ___________
intermolecular energy
The device in which the kinetic, potential or intermolecular energy held by fluid is converted in the
form of mechanical energy in a rotating member
TURBINE
an equation derived from the first law of thermodynamics of
steady flow open system used to determine the mass flow rate and volume flow
rate of fluid
Continuity equation
a system used to move liquid at low pressure elevation to high pressure elevation
pump
a machine for moving a liquid, such as water, by accelerating it radially outward in an impeler to a surrounding volute casing
centrifugal pump
a pump in which motion and pressure are applied to the fluid by a reciprocating piston in a cylinder
reciprocating pump
also known as piston pump
reciprocating pump
a displacement pump that delivers a steady flow by the action of 2 members in rotational contact
rotary pump
also known as vertical turbine pump
deep-well pump
the height to which a column of fluid must rise to contain the same
amount of energy as is contained in one unit weight or mass of fluid under the conditions
being considered
HEAD OF FLUID
Is a head based upon the elevation of the fluid above some arbitrarily chosen datum plane
Potential or Actual Head
Is a measure of the kinetic energy contained in a unit mass fluid due to its velocity and is given by
the familiar expression for kinetic energy
Kinetic or Velocity Head
Is the energy contained in the fluid as a result of its pressure
Pressure Head
an equation used to
determine the head of fluid
Bernoulli’s equation
