- Why don't you use easy metric system???
presure and imperial is just crap.
- presure doen't need to be calulated on the length of the tube... If you put a wire in the ground, will you calculate the total weight above it? If I make a fifty km wire out of 1kg of coper, dig it 5m in sand in the desert, will you calculate the weigh the machine need to move section per section it opens or like the machine is holding it all above ground?
It is more that time that Europe start to understand that the US are not ally
