Old Moskvich 403 for sell.

Two weeks ago I found this car



Very old model of Moskvich 403. It is a made in 1960 years and still working normally. It can ride and only the tires are little bit worn out. Of course the owner trying to sold it many times but with lack of success, because in Bulgaria no one buying this cars. Now I will try to sold it abroad where car could meet the real connoisseurs.

I have decide help him to sold this ancient car because I think this kind of cars must be driven not only stay on the garages. Of course it could be driven only after little repair which will not cost so lot.

How to convert Fahrenheit to Celsius degrees.

These days I was invited to flick through project for installation which incinerates wastes. The company which developed this project is from USA and I was very disappointed that most of the temperature currencies in the papers were in Fahrenheit. It is normal of course for people who live in other side of Atlantic Ocean but for most of the Europeans this digits are totally useless.

So let’s see how to convert from Fahrenheit to Celsius. The formula is very simple:

[⁰C] = ([⁰F] – 32) x (5/9)

One example f course

If [⁰F]= 32 then [⁰C] = (32-32) x (0.555)= 0 ⁰C

The easiest way to remember this is when you see the value in F just deduct it with 32 and then divide the value by 0.555 or 5/9. It is not so correct but always works.

There is a very interesting fact to know that when you have temperature - 40 ⁰F
the value in the Celsius is the same - 40 ⁰C, but of course everything could be described with mathematics.

Here some web resources for on line converting.

Converter which I made

Interactive Thermometer - funny tool

ppm - mg/m3 calculator

I have prepared simple calculator for those who want to make a one or three calculations and to convert from ppm to mg/m3. In Google docs I put three sheets one for ppm to mg/m3 other to be easy calculating the molecular mass of the compound and third is to convert from m3 to Nm3.


Here are the sheets

How to convert from m3 to Nm3?

Many times when you see the different concentrations of any polluters you may see it in mg/m3. For people who are not familiar with terminology this could be a little bit disturbing because some norms and limits are granted in mg/Nm3 which in some cases could be totally differen t.Where is the difference in this upper case N? N means Normal and according to International Union of Pure and Applied Chemistry and their site these standard conditions are temperature 273.15 K (C) and pressure 10^5 Pascal’s.

And what we should to do if have a concentration of 300 mg/m3 and limit of 150 mg/Nm3. Is it possible to reach the norm and even to outrun it? Yes in some cases it is possible but not in any of course. We can look our concentration and just to imagine that this concentration had measured in some chimney where the smoke gases became from furnace with temperature of 850 – 950 (Klaus process for example). And you have measured something like:

T (average): 650 ⁰C

P (average): - 3 mm Hg

T_o = 273 K – this is normal temperature – 0 ⁰C

P_o = 760 mm Hg – 1 atm.

Other common measured parameter is a flow of smoke gases which is possible to be something like 130 000 m3

Then from these we are able to find some coefficient (let’s name it - K)

K = (T_o * P)/( P_o *T) = [273*(760-3)]/[760*(273+650)]= 0.29

Now we should convert 130 000 m3/h * 0.29 = 37 700 Nm3

See how low are now these – round three times less than before. If we have measured the humidity in the chimney gases in percent then we also should remove this. It happens at this pattern:

If humidity is 5 % for example so then 37 700 Nm3 must multiple to this 5% and

37 700 * 0.05 = 1 885 Nm3 and

37 700 - 1 885 = 35 815 Nm3

At the end from 130 000 m3 we receive 35 815 Nm3 of chimney gases.

Vacancy in Canada

Yes!
I was in Canada for three weeks. Since 28 August to 16 September. It was wonderful experience. I have visited the Niagara and the capital of Canada - Ottawa. You are able to see some pictures

here.

I think they should be a most detailed than me.

And I promise in next my topic I will explain "How to convert from m3 to Nm3" and so on...
