Let's try to understand why this happens: due to technical problems, engines that run on gasoline only lose income when the percentage of alcohol exceeds the 25% mentioned above. To avoid problems, both fuel distributors, as the supervisory bodies and consumers, have the right to require the determination of the amount of alcohol in gasoline. To avoid buy "pig in a poke" there is a fairly simple procedure: Grab a 100mL beaker and add 50 mL of water and 50 mL of gasoline and agitate. The result will be an increase in the watery part because alcohol is more soluble in water than gasoline. Calculate the percentage of alcohol and make sure it is in accordance with the specifications (up 25%). Example: gasoline water The difference (65-50 = 15 ml) of alcohol is the amount that was present in 50 ml of gasoline. Therefore we have: 50 mL (gasoline) - 15 ml alcohol 100 mL (gasoline) - X mL alcohol Result: gasoline is adulterated One needs generated by contemporary society is the availability of good quality electricity, efficiently and without risk of supply interruption. One solution to this requirement is enabling modern thanks to new technologies that employ natural gas. He is an old acquaintance of civilization and should not be confused with the cooking gas, which differ by their chemical composition and properties. Natural gas mainly consists of methane (CH but contains small amounts of ethane (CH CH propane (CH CH CH Typically, the gas is transported by pipeline from its source to domestic consumers, who use it for cooking and heating. Another use for natural gas that is being stimulated by the government is in power plants, where its burning with little waste generates electricity quality.

Pokušajmo razumjeti zašto se to događa: zbog tehničkih problema, motori koji rade na benzin samo gube prihode kada je postotak alkohola premašuje 25% gore spomenuto. Da bi izbjegli probleme, oba goriva distributere, kao nadzornih tijela i potrošača, imaju pravo zahtijevati utvrđivanje iznosa od alkohola u benzinu. Da biste izbjegli kupnju "mačku u džaku" je prilično jednostavan postupak: Grab 100ml čašu i dodajte 50 ml vode i 50 ml benzina i uzburkati. Rezultat će biti povećanje u vodenom dijelu jer alkohol je topiv u vodi od benzina. Izračunajte postotak alkohola i pobrinite se da je u skladu sa specifikacijama (do 25%). Primjer: benzin voda Razlika (65-50 = 15 ml) alkohola je iznos koji je bio prisutan u 50 ml benzina. Stoga imamo: 50 ml (benzin) - 15 ml alkohola 100 ml (benzin) - X ml alkohola Rezultat: benzin je krivotvorena Jedna potrebama koje generira suvremenog društva je dostupnost kvalitetne električne energije, učinkovito i bez opasnosti od prekida opskrbe. One rješenje za ovaj zahtjev je omogućavanje moderne zahvaljujući novim tehnologijama koje zapošljavaju prirodnog plina. On je stari znanac civilizacije i ne treba miješati s plin za kuhanje, koja se međusobno razlikuju po kemijskom sastavu i svojstvima. Prirodni plin se uglavnom sastoji od metana (CH ali sadrži male količine etana propan CH CH Tipično, plin transportira plinovodom od izvora do domaćih potrošača, koji ga koriste za kuhanje i grijanje. Drugi koriste za prirodni plin koji se stimulira od strane vlade u elektrane, gdje je njegov gori s malo otpada generira struju kvalitetu. METANA STVORIO PREGLED OTPADA METANA DOBIO Ulje depoziti
