how is it possible that this happened the way that it did at the twin towers?as american people we need better answers. iam bothered because i really do believe that we are not being told the truth about what happened, mainly because the facts do not support the story given and also the pentagons hole in the wall that measured close to 20 feet in diameter,how big in diameter is a jumbo jet???? any parent that had a child come home with a story like this where the facts did not support the story given, what would the parent think? why are we as adults expected to be any different? you can call me a conspiracy theoryist if you want ,but the reality is something smallerthan a jumbo jet made that hole in the pentagon and the twin towers,they sure fell awful quick,that heat from that jet fuel got up to 1800 degrees and made all those floors fall in repetition, is that what the facts represent? certainly mean no disrespect to the familys of those who were lost / just trying to sort it out

Hello everyone

My last question may be a little misleading and I couldn't respond to my own question so please forgive me when I rephrase it again.

I have a 65w stepdown Input230/240 AC, Out: 115V AC. 65VA transformer and I wanted to know if I should be concerned about how much electricity the transformer draws just by the fact that it is plugged into the wall socket even when the hardware connected to it is not on.

I don't need an exact figure. Just a layman's terms as what your typical transformer would draw. An absolute average idea of the average transformer.

If I turn the transformer off, all my appliances will need to be reset when I turn the transformer back on again.

So does an average one consume as much as a light bulb, or say... something much more.. like a computer etc.

I just need a general idea. Thank you.

The air flow exhausted out of a room with dimensions 30’ x 30’ x 10’ is 4500 cfm. Calculate the number of air changes per hour. What do you know about the relative safety of this room with regard to the concentration of a solvent evaporating in this room, based on the ACH value? What happens to the number of ACH if the room volume was half the original amount? What does this changed ACH tell you about the concentration in the smaller room compared to the larger room, at equilibrium conditions?
