PRESENTATION TOPIC
REVOLUTION SPACE REQUIRED FOR TURBINES AND CAR AXLE
SPACE REQUIRED THE SPACE REQUIRED FOR
REVOLTION OF TURBINE BLADE CAN BE DETERMINED FROM THE VOLUME OCCUPIED BY THE BLADE DURING ITS REVOLUTION.
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.
FORMULAE
First, the inner radius is NOT x. The distance from the x-axis 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
CALCULATING VOLUME
outer radius is
Putting values in this formula we can get volume.

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.

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….
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
CAR AXLE
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.
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….
