2. TURBOMACHINERY
• Turbomachinery, in mechanical engineering,
describes machines that transfer energy between
a rotor and a fluid,including both turbines and
compressors.
• A turbine transfers energy from a fluid to a rotor,
a compressor transfers energy from a rotor to a
fluid.
• Centrifugal pumps are also turbomachines that
transfer energy from a rotor to a fluid, usually a
liquid, while turbines and compressors usually
work with a gas.

3. TYPES OF TURBO MACHINES
• In general, the two kinds of turbomachines
encountered in practice are open and closed
turbomachines.
• Open machines such as propellers, windmills,
and unshrouded fans act on an infinite extent
of fluid. whereas, closed machines operate on
a finite quantity of fluid as it passes through a
housing or casing.

4. • Turbomachines are also categorized according to
the type of flow.
• When the flow is parallel to the axis of rotation,
they are called axial flow machines.
• When flow is perpendicular to the axis of
rotation, they are referred to as radial (or
centrifugal) flow machines.
• There is also a third category, called mixed flow
machines, where both radial and axial flow
velocity components are present

5. • Turbo machines may be further classified into
two additional categories:
• Those that absorb energy to increase the fluid
pressure, i.e. pumps, fans, and compressors
• Those that produce energy such as turbines by
expanding flow to lower pressures.

8. HYDRAULIC MACHINERY
• Hydraulic machines are machinery and tools that
use liquid fluid power to do simple work. Heavy
equipment is a common example.
• In this type of machine, hydraulic fluid is
transmitted throughout the machine to various
hydraulic motors and hydraulic cylinders and
which becomes pressurised according to the
resistance present. The fluid is controlled directly
or automatically by control valves and distributed
through hoses and tubes.

9. • Hydraulic machinery is operated by the use of
hydraulics, where a liquid is the powering
medium.
• The popularity of hydraulic machinery is due
to the very large amount of power that can be
transferred through small tubes and flexible
hoses, and the high power density and wide
array of actuators that can make use of this
power.
