HOW ADDICTED WE ARE ON TECHNOLOGY

In olden days the doctors check our pulse rate by placing their thumb on our palm joint based on pulse behavior they told what the problem we are having.

In now a days if you visiting a hospital for treatment ,doctors asked us what the problem we are having ,we must tell otherwise they don’t know, otherwise they are find out problem by using technology (EEG,ECG,BP test, blood tested,etc)

See how human beings addicted on technology .

HATS OFF TO THE TECHNOLOGY

”In kargil war Pakistani soldiers wearing PV jackets to fight at night. Whereas we our soldiers not having proper shoes” .am not say this for criticizing Indian army. But Indian government fails to encourage technology till now.

“When they are going to realize?????, I have no answer for that question, But One day they definitely realized .then let’s see when did the day comes?”  

how to utilize energy efficiently

Hi friends do u know  the healthy power system symptoms:

1)voltage profile (0.95pu TO 1.05pu),i.e 5% variations

2)frequency profile(0.975pu TO 1.025pu),i.e 2.5% variations

Note:pu-per unit

But in India almost power lines operates at 0.78-0.8 pu, even some time 0.7pu also

But the Transco, disco officers says that it’s also healthy

Govt. working timings for Transco, genco, etc. are 9am-5.30pm, but they limited to 11am-3.30pm, then how could we get 0.95pu voltage healthy condition????

Because of the reason the generators never gives 100% output, I mean 100Kw generator gives only 80Kw only.

I practically recheck myself in my village and my house I got 215volts instead of 230v, even my house load is located nearer to transformer.i.e voltage drop of line almost negligible. And some time it may be 205 also. Then what’s the appearing voltage to the houses which are connected at end I don’t know.

Yemundile bayya idhanta common ani anokovadhu friend, due this effect we our houses takes higher current to makes power balance P=↓V*i↑,i.e high unit consumption ,higher current bills(TARIFF) even lesser loads

So what we supposed to do

1. Reduce load as low as possible. I mean ON the loads what u really want, if u do so, you are the one reducing current bill&&same time u r saving power to future generation.

2. Use heavy loads in home like grinders, mixes, and heaters at 2-φ power given to villages. Because at that time u get around 220 v, at time of 3-φ power fed, due to running of all agriculture motors, we get 205v at terminal, it makes higher current required to run load.

3. Replace your old lights by LED(light emitting diode bulbs) or CFL(compact fluorescent lamps).

It illuminates 60W normal bulb lighting with 9W CFL&&6W LED. See how much we can save.

4. Replace CRT TV’s by LED or LCD screens, use energy efficient motors, utilize solar energy for cooking ,heater’s ,power supply’s

5. Try to maintain proper earth at transformer of your village, by pouring some salt water.

6. try to use solar cell based ups to share your load. An especially village persons, why can’t we fill our roof’s with solar panels.

Energy conservation

Energy conservation is cheaper than energy generation and utilization.

How it cheap???????????????

Let’s take an example: money saving is cheaper than money earning.  Why?????????

Because if you earn money you to pay income tax. If you save, I don’t think any income tax in most of the countries in the world, I don’t know about all countries,” there may be a country, hey!   why are u saving money pay some tax”.   I am not heard such a country yet.

Like the way if you generate u need to transmit, there may be losses and utilize you to pay tariff. And if you save, no tariff for that. 

TIPS FOR MAKING HOT WATER AS HOT AS LONG TIME FOR VILLAGE PEOPLES

for that perpuse no need to use flasks are any equipment to restrict heat tranfering.
1)add small amount of cold water to hot water when you are placing at outside to use
2)place the hot water with bowl inner layer with block coated paint.
caution:dont place water on the bowl with outer layer as block.  generally in villages we having
wood burning stoves.which produce lot of co2 emissions and ash content,which makes the bowl
 as make block colour at outer layer.generally this type of bowls can tranfer heat quickly
due to outer layer as block
above tips for not only water and its applicable to any hot conents also

do you observe this???????
if you put bowl with hot water placed at outside environment.
                  &&&
and place another bowl with hot  water and add some amount of cold water to mix.
and place same environment.

what you observed


we can obseve that the pure hot water bowl lost the hotness very steep maner.
but    the mixed water content can looses the hotness very slowly


why????????????????????


very simple!  the heat can transfer quickly in solids(bowl) next liquids(water),
next gasses(air)

heat tranfering rate lets say HTR
HTR(bowl)>HTR(water)>HTR(air)

1)the bowl with pure hot water directly contacted to earth through base of bowl.

heat can tranfer with the high rate equals to HTR(solids)

2)the second bowl with mixed content of water(hot+small amout of cold)
dont having direct contact with earth
why ,because the small amount of cold water dips in hot water and
make a layer at base of bowl its makes a resistive to heat compare to solid
note:cold water weighter than hot water(atoms expens to aquiring energy of heat energy)

here heat transfering through water layer so HTR(water)<HTR(Solid),sooooo heat tranfering was slow.
