Watt (W) is the unit of tension. Kilovati and megavati. What is kilowatt-year
Choosing a hair dryer, a blender or a pilosos in the store, you can remember that numbers with the Latin letter W are entered on the front panel. Chi just such a firmness? Could it be some kind of publicity stunt? How to decipher W and what is the value? Let's find out the answers to all questions.
Appointment
Vishchezgadana letter - ce Latin abbreviated as well known to everyone from the lessons of physics - vat (watt). Vіdpovіdno to the standards of the international system СІ, W (W) є alone in the case of tightness.
If you turn to the power of the characteristics of the butted electrical appliances, then the higher the number of watts in any of them, the tim wines are tighter.
For example, there are two blenders in the window with the same size: one of them is a popular brand at 250 W (W), the other one is a smaller blender, but with a higher pressure at 350 W (W).
Qi numbers mean that the other one is more detailed or the product is faster for the first stretch of one and the same interval of an hour. To the one who buys for us, security is important to the process, so choose another option. As if speed does not play a key role, you can choose the first one, like the last one, maybe, long-term.
Who Vigadav Vikoristovuvati Vati
It’s not marvelous to sound today, but before the emergence of loneliness, the fatigue was practically overcome by the whole world of kіnskі forces (c.s., English - hb), usually foot-pound-force per second.
The names of Vati were in honor of the person who invented and made a single one - the Scottish engineer and winemaker James Watt (James Watt). Through the sentences, the term abbreviated is written with the capital letter W (W). The whole rule is worth being alone in the SI system, called the nickname of the scientist.
The name, like the loneliness of the world itself, was first officially looked at in 1882. at Great Britain. After a few trohi less than a hundred years, cotton wool was needed to be accepted by the whole world as one of the units of the International System І (it happened in 1960).
Formulas for the meaning of tightness
From the lessons of physics, there are a lot of people who remember different tasks, for which it was necessary to shake the strain of the struma. Just like that, so and today victorious for a joke wat formula: N \u003d A / t.
Won was deciphered as follows: A - tse kіlkіst roboti, divided into an hour (t), stretching out like a vikonan. And how else to guess that the robot is measured in Joules, and the hour is in seconds, so 1 W is 1J / 1s.
The examined formula can be changed a little. For this varto, I’ll guess the simplest scheme for the significance of the robot: A \u003d F x S. It’s good to go out of it, that the robot (A) has a good rank її (F) on the way, passing the object under the injection of given force (S). Now for the meaning of tightness (vat) the first formula is one after the other. Exit: N = F x S / t.
Long single wat
Having sorted out the questions “Watti (W) - what is it?”
When preparing vimiruvalnyh devices for medical purposes, as well as important laboratory data, it is necessary that the stench be less accurate and sensitive. Adzhe vіd tsogo lie not just a result, but if the life of a person. As a rule, the linings of "strange" apparatuses require a small amount of tension - dozens of times less cotton wool. Sob not to be tormented by steps and zeros, for її vicory is assigned lower singles: dW (decivati - 10 -1), cW (santivat - 10 -2), mW (militation - 10 -3), μW (microbed - 10 -6 ) ), nWt (nanowatts -10 -9) and more sprats of others, right up to 10 -24 - ІWt (ioktowatts).
From the greater number of rehabilitated more alone, a great person does not stick in a pobut. As a rule, only former seniors work with them. Also, these values appear in various theoretical roses.
Wati, kilovat and megawati
Razіbravshis іz dolnymi, varto look and multiple singles vatіv. With them, the skin of a person tends to douche often, heating water in an electric kettle, charging a mobile phone, or concocting other rituals.
In total, on this day, we have seen about a dozen such units, but they are widely seen only two - kilowatts (kW - kW) and megawatts (MW, MW - in this case, put the capital letter “m” in order not to confuse the unit with milliwatts. mW).
One kilowatt is a thousand watts (10 3 W), and one megawatt is a million watts (10 6 W).
Like in the case of long-term singles, and in the middle of multiples, especially, as if they are less likely to be in high-profile enterprises. So, at power plants, GW (gigavat - 10 9) and TW (teravati - 10 12) are sometimes generated.
Krіm is more important, petavati (PVt - 10 15), eksavati (EVT - 10 18), zettavati (ZVT - 10 21) and iottavati (ІVT - 10 24) are seen. Like and especially small longitudinal units, great multiples of vicorist in the main with theoretical roses.
Watts and watt-years: why is it important?
Although on electric appliances the pressure is shown by the letter W (W), then when you look at the largest electric heater on the stove, you can see something else short: kW⋅h (kW⋅year). It is deciphered as “kilovat-year”.
You can see them and wat-year (Tu⋅h - W⋅h). Varto turn respect, that according to international and domestic standards, similar ones are recorded for a short-lived look only with a dot, and for the full version - through a dash.
Watt-year and kilowatt-year є v_dm_nimi units in W and kW. The difference lies in the fact that with the help of them it is not the intensity of electricity that is transmitted, but it is out of the middle. Tobto, a kilowatt-year-old shows, like the very її kіlkіst bula was broken (transferred to a vikoristan) in one hour (in a given moment in one year).
