REVOLUTION SPACE REQUIRED FOR TURBINES
AND CAR AXLE

3. 

SPACE REQUIRED
THE SPACE REQUIRED FOR
REVOLTION OF TURBINE
BLADE CAN BE DETERMINED
FROM THE VOLUME
OCCUPIED BY THE BLADE
DURING ITS REVOLUTION.

4. BASIC CONCEPT FOR
CALCULATING
VOLUME

We rotate THE GIVEN CURVE
about a given axis to get the
surface of the solid of
revolution. For purposes of
this discussion let’s rotate the
CURVE about a line. Doing this
for the curve above gives the
following three dimensional
region.

5. First, the inner radius is
NOT x. The distance from the xaxis to the inner edge of the ring
is x, but we want the radius and
that is the distance from the axis
of rotation to the inner edge of
the ring. So, we know that the
distance from the axis of
rotation to the x-axis is 4 and
the distance from the x-axis to
the inner ring is x.
INNER RADIUS: 4-X

6. outer radius is
Putting values in this formula we can get
volume.

8. GEOMETRY OF
BLADES OF
TURBINE
blade of turbine is
shown in figure

9. WIND MILL TURBINE
TURBINES

A turbine is a rotary
mechanical device that
extracts energy from a fluid
flow and converts it into
useful work. A turbine is
a turbo-machine with at least
one moving part called a rotor
assembly, which is a shaft or
drum with blades attached.
Moving fluid acts on the blades
so that they move and impart
rotational energy to the rotor.

11. VOLUME FOR
REVOLVING A
BLADE OF TURBINE


The volume occupied
by revolving this blade is
actually the space for
turbine revolution.
The geometry of the blade
shown in figure .now we
assume that geometry as
two functions overlapped
and forming a region. We
take one side of the blade as
on function and other side
as other function..
So the same FORMULAE
would be followed….

12. SPACE OCCUPIED BY
BLADE OF TURBINE
SO KNOWING THE OUTER
AND INNER RADIUSWE
CAN FINF AREA THEN
VOLUME.
SO BY PUTTING
FORMULAE IN THIS WE
CAN FIND THE VOLUME
OCCUPIED BY THE
REVOLUTION OF THAT
BLADE

13. CAR AXLE

14. 
CAR AXLE
An axle is a central shaft for a
rotating wheel or gear. On
wheeled vehicles, the axle may
be fixed to the wheels, rotating
with them, or fixed to its
surroundings, with the wheels
rotating around the axle.

15. 
SPACE FOR
REVOLVING CAR AXLE

The geometry of the CAR
AXLE shown in figure
.now we assume that
geometry as two
functions overlapped and
forming a region.We take
one side of the blade as
on function and other
side as other function..
So the same FORMULAE
would be followed….
