INTRODUCTION:
Vacuum can be defined as a space from which the air has been removed, thus
containing very few particles of matter. A perfect vacuum contains no matter at
all, but for practical purpose soft or low vacuum is defined as down to 10-2 Pascal
and hard or high vacuum is as below this, ultra high vacuum is lower then 10-7
Pascal, while atmospheric pressure is 101325pascal or 100kpascal approx.
THE IDEA:
Till now not much work is done in field of practical use of vacuum, the work is
only done for creating the vacuum.
My idea is to use vacuum in practical purposes for increasing the efficiency of
rotating machines. The idea is very simple, as we know that vacuum is void and
it contains nothing, not even air particles. Hence if we make any fan or flywheel
etc. to rotate inside vacuum, the fan or flywheel will exert no air friction resulting a
certain increase in rpm as compared to standard temperature and pressure.
If we stop the external power supply then also the fan will not stop rotating, as
there is no air friction to oppose its rotation.
Hence with just one stroke of energy we can start the rotation and carry on those
rotations even when the power supply is switched off. It will surely going to save
a lot of energy. So this vacuum can really increase the efficiency of any rotating
machine, and finally we can come over the energy crises…
KEY WORDS: vacuum, rotating machines, air friction, rpm.
I. INTRODUCTION:
Vacuum can be defined as a space from which the air has been removed, thus
containing very few particles of matter. A perfect vacuum contains no matter at
all, but for practical purpose soft or low vacuum is defined as down to 10-2 Pascal
and hard or high vacuum is as below this, ultra high vacuum is lower then 10-7
Pascal, while atmospheric pressure is 101325pascal or 100k pascal approx.
II. THEORY:
The theory I have got is very simple it involves the basic fact that vacuum is void
and it contains nothing not even air particles. My idea is to use this property of
vacuum by making any fan, flywheel, turbine etc. to rotate inside the vacuum, the
fan, flywheel, or turbine will exert no air friction resulting a certain increase in its
rpm as compared to standard temperature and pressure. Its other main feature
will be; even if we stop the external power supply then also the fan will not stop
rotating, as there is no air friction to oppose its rotation.

3. III. THE SET UP:
Fig. practical setup
The practical setup I have planned is very simple, it consists of:
1. dc motor
2. a fan or turbine
3. vacuum gauge
4. vacuum cleaner as sucker to create vacuum
5. a tube in which vacuum can be created
there will be a shaft connected to motor which contains fan or turbine can be
made to pass through the vacuum tube, and the result in change in the rpm and
the stopping time of motor can be compared by nothing down the rpm and the
stopping time at standard temperature and pressure and then noting down the
rpm and the stopping time inside the vacuum tube.
Hence we will be note the following observations while performing the test by
gradually decreasing the pressure inside the tube:
1. pressure
2. rotations per minute
3. time taken by the turbine to stop after power supply is switched off.

4. IV. THE EXPECTED RESULTS:
Keeping in mind the fact that inside vacuum tube there will be no air pressure or
friction to oppose the rotation of fan or turbine, therefore there will be a definite
increase in rpm and stopping time of the motor with decrease in pressure.
Hence we can conclude that:-
p∝1/rpm ….(1)
p∝1/t ….(2)
where
p = pressure
rpm = rotations per minute
t = time taken by the turbine to stop after power supply is switched
off.

5. The expected graphs can be plotted as:

6. V. APPLICATIONS AND DRAWBACKS
This setup can be used or applied in many fields such as power generation
plants etc. rather it can be used where ever any rotating body is present. We can
use this setup to save a large amount of energy.
The main drawback with this setup is problems to create vacuum. But with
modern techniques it’s not going to give us a lot of trouble.
VI. CONCLUSION:
By using this type of setup we can practically use vacuum in increasing the rpm
and efficiency of any rotating body, and hence can save lot energy. So who
knows in future your bikes and cars can have these small setups to increase the
speed and more importantly the millage. The big power plants can also use it to
increase their production.
