Hydrogen fluoride is a chemical molecule formed from the covalent bonding of hydrogen and fluorine atoms. This article discusses the many uses of hydrogen fluoride, as well as the potential dangers of exposure to this chemical.ydrogen fluoride is a molecule that is formed from combining a hydrogen atom with a fluorine atom. It is a highly valuable molecule in industry, but is also a very dangerous chemical for biological systems.
How much Engine Horse Power does an Alternator need to make Electrical Energy? How much power does it take to run an alternator? An alternator typically takes about 1 HP (horse power) for every 25 amps of power generated. So, a 100 amp alternator will require about 4 HP at full output. Most alternators do not operate at full output for very long.
An original equipment alternator will put out between 60 and 120 amps at 2000 rpm. Let's assume that the headlights, fans, and radio are all on and using up half of this power. So in this worst-case example it is going to take about 20x the amount of time spent cranking or about 10 minutes to replenish the battery. In more realistic scenarios the starting load will be much less as will the cranking time, and the energy used to start the car will be returned to the battery in a minute or two.
