Hormones and "Relative Humidity (RH)"... ---- Will be fun!

Yesterday, while enduring the absolutely tiring drive from Edsa Shangrila to Sucat, at the peak of rush hour about 8pm, I was talking to my two lady passengers about this thing I read on Facebook some time ago about what happens to men and women who have their first baby. I told them that the article mentioned that when a man and woman have their "Unica and or "Unica Hijo" , their hormones drop by 50% as studied by some doctors. A man looses 50% of his testosterone and 50% of estrogen for women but the article also mentioned that it eventually recovers indefinitely until the baby is old enough to at least be less dependent of the parents as a baby. This, as what the article mentioned is a way for nature to make sure that the offspring is taken care of so that the parents will focus more on the 1st born rather than making a new one immediately after.

Ok, so, after I shared that to my passengers, immediately I was asked "how about those people who have a second baby right after the first? Then i replied, "Nature might have been asleep at that time? It was past midnight perhaps?" Hehehe just kidding. 


I'll tell you what I said at the end of this blog post so that I could have your attention... Or you could skip this for now and move on ahead if you don't have the patience.

The reason for holding you up is that I wanna first share something about the topic "Relative Humidity" 
..

Right now you are confused and in your mind you have your voice in your head telling you...
"WTF, this guy is effing crazy... Starts of with hormones and then WTF is relative humidity??"

Well, if your are a Mechanical Engineer and or studying and prepping up to become one, you know this right? Your professor might have mentioned to you that it's "the ratio of the partial pressure of water vapor in the mix of air and water to the saturated vapor pressure of water at a given temperature " or perhaps you know it as the curves in the psychometric chart that has numbers from 10%-100% that is labeled as "relative humidity". You might even know it as the formula in the screenshot below:



Or in general you might know it as the thing that the weatherman reports to indicate how wet the air is?

Well, I'm not here to explain this to you with all the technical stuff. I'm here to put it  in a simpler way so that you would know what the concept is rather than the technical definition. Furthermore, I'm here to relate this to my introduction. Hehehe

Ok, so, lets begin!

Just in case you didn't know, let me first tell you that the air your breathing is not entirely Oxygen.
It Is a mixture of many things and whatnot. I won't tell you what the other things are but let's deal with only two (2) things that are important to HVAC or whatever. 

The air you're breathing has two things:

1. Oxygen (obviously coz it's air - or simply"air")
2. Water vapor (steam or "invisible steam" because you can't see it)

Well, you can't actually see both but the "water vapor" you could when it's cooled and condenses. When you see it you then simply refer to it as "water". It's the little droplets of water you see outside the bottle of your favorite beer (no, the bottle is not sweating... it's science magic!)

Ok, so now that we have establish that, let us now move forward with "relative" humidity".

Relative humidity simply is a ratio of how much water vapor is there in the mixture with the total. For all you visual people out there, please refer to below image:


Lets just say that the water part of this image is the "invisible steam" I referred to earlier.
Since the bottle is both half empty and half full then if this were the "air mixture" we talked about then this would have been measured at 50% relative humidity.

If the bottle is full, then we measure it at 100% relative humidity.


If the bottle is filled quarter way then we say that it's 25% relative humidity.

So on and so forth....

Ok, I hope you understood that, just know that it's a ratio and don't be confused and or think that it's an indication of how "wet" or dry the air is and I'm here to explain why:

Since its only a "ratio" it doesn't give us any idea on how much "invisible steam" we really have. Think of this in another way and now let's use measurements on it.

Ok, let's say we have a 1 Liter bottle of Coca Cola and its half empty and half full. We correlate that to RH(relative humidity). The same as our analogy above then the RH is equal to 50%.
This time, since we know that it's 1 liter bottle then we can say that the "invisible steam" is 500ml.

But, what if we have a 2 liter bottle? Wouldn't the end result still be 50% RH if its the same? But this time look at the amount, the "invisible steam" in the 2 Liter bottle would be 1Liter. 

So, this just serves as a reminder for people who design their cleanrooms and whatnot that base their design on RH and not on the actual "grains of moisture per lb of dry air" measurement.


Moving on.......

Ok, so for all you guys who didn't skip and wants to now what I said as a reply to the question "what about those people who have kids immediately after the first born:

"Ok, let's just say that indeed people loose 50% of their hormones after the first born... Now, since people are built differently then the amount of the actual hormones varies....consider a person lets say who has 1 Liter of hormones, when he/she looses 50% then what's left is 500ml and at that level it's impossible to have a second child. Then consider someone having 2 Liters of hormones and loosing half means he would still have 1Liter and its considerably more than the other person right?"

Well, WTH, the story indeed connects huh?

Hehehe
Thanks thanks!
I hope you enjoyed reading!

-Love much!
