Ok; All normal pressure gauges measure "gauge pressure". This is the difference between atmospherics pressure and the pressure inside whatever you are measuring. At sea level, the atmospheric pressure is about 14.7 Psia. So a pressure gauge will read zero. At elevated altitude the atmospheric pressure is less, so if you pump up a tire at sea level, the tire will have a higher degree of inflation at a higher altitude. Imagine that you inflate a tire at sea level and then put it into a chamber pressurized to 1000 psi. The tire will be about as big around as a pencil (insert your own word). If the sea level pressure was 30 psig, then the tire would now have to be inflated to 1030 psi to maintain the same shape as it was originally. If the gauge was used in the chamber with the tire it would read 30. The difference in the original question would amount to 2-3 psi. Really Bill Ahrens Sent from my iPad

Example We have all (most) done....."as kids" Put a balloon inside your mouth backwards and suck hard on it,...... it IN-flates. Pressure?...what???? a new thread that is spreading like a wild.......Oil thread. (lol.)

For Laws on pressure you want to include "Pascal's Law"

Simple thought would be, If a gas is trying to EXPAND, But is restricted, woulded the pressue be differant,...greater? Simple test, We ALL, meet in Colorado springs, Buy a bag of potato chips, (I'll buy) fell the softness of the SEALED bag,Take it to the top of Pikes Peak, (14,115ft.) andf see how the bag expanded and got FIRMER. (you can thump it with your finger and hear the differance.)

In the late 70's, my oldest brother took his wife on a road trip vacation from here in Columbus, Ga. to Colorado. They'd purchased picnic supplies before leaving. In CO for a picnic, they stopped to eat in the car. Beth reached for the mustard and before my brother could say "Wait!", she untwisted the top. Whoosh! He had a heck of a time cleaning mustard out of his car's headliner. -eddie

And how old are you??? It's amazing that no matter how old WE get, or how we relate to others, older or younger, OUR Siblings, are always defined as...... "MY older,younger, little, big. (and to often respect of wisdom 7 Knowledge, given, is also based on this.) My Nephew asked Why I call my LITTLE, OR BABY brother of 6ft. 7inchs these titles. He just said, "I just learned to live with it, It's NEVER gonna change. I'm only 6ft and 1/4 inchs. (1/4inch?? competing with 6, 7" I took claim what I can. LOL) PS. He has a GROWING bold spot, I have a FULL set of hair. Maybe shortness has it's benifits??

I have a "Baby brother " who is 65, they get used to it. Also I think that one benefit of being so short is that you don't bump your head and disturb the hair as much. The tallest member of my tribe is about 5' 9", and I stand a towering 5'7", so I understand "short" DC DC
