I want to know does the sentence below make any sense to you?
The heat coefficient is orders of magnitude lower than the corresponding region before the critical heat flux was exceeded, due mainly to the lower thermal conductivity of the vapour.
I just can't understand what means "is orders to"? and the rest of the sentence seems so complicated.
"Orders of magnitude" refers to whether or not the numbers are in the same range, represented by the same number of digits. If one is 7 and the other 3, they are both in the same order of magnitude. But if one is 7 and the other 35, then they are not. If one is 7 and the other 3467, then they are separated by several orders of magnitude.
