This is awesome!

5 cents about pressure (metric..)

1 [bar] is 1kg per square centimeter.

Under water, the "column" of water pressing on one square

centimeter at a depth of 10 meters is ten times one hundred

times one cubic centimeter; which is one liter of volume - or

one kilogram..

One cubic meter of air weighs 40 grams, if I´m right.

(I´m not: it´s 1293grams!!!!!!!!)

Normal atmospheric pressure is 1 bar (1kg/cm²)

- a column of air, 1000 x 100 (cm) x 1cm³ of air

(which is 1/10th of a cubic meter) should weigh

100.000 times 1,293kg/1.000.000 which is 0,1293kg- or 129 grams

(which simply is 1293 grams divided by ten..)

- so an altitude of 1km is reducing power by rd 13% I guess.

This is what Wikipedia says:

Troposphäre from sea level up to 7 km (Polar region) and 17 km (Tropen), begrenzt durch die Tropopause

Stratosphäre bis zur Stratopause in 50 km Höhe

Mesosphäre bis zur Mesopause in 80 bis 85 km Höhe

starting from 1bar=1kg/cm² - which is the pressure of that air "lake"

we live in, an atmosphere of linear density would have to be

1000g/1293g= 773 meters..

Bull**** Alert! EDIT:

1m³ of air weighs 1,293 kg/m3; to stack that up a column 1x1cm of

7,733km is needed.. - sorry, woke up today remembering the feel

sth was wrong with these calculations..

But in reality it´s this:

reality is pretty interesting.. thanks for making me think about this!

kind regards,
