Question

What is the height of a constant density air column that produces standard pressure at its base? P=pgh. Air (STP)=1.2982kg/m^3

Answer 1

Pressure=(density of air x gravitational constant x height)
Density of air at STP=1.2982 kg/m^3
Gravitational constant=9.81 m/s^2
Pressure in STP=101,325 Pascals or N/m^2
Now you can find h.

Answer 2

g is gravitational constant
h is height
P is pressure
p is density of air.
