Question:

The variation of fluid pressure with height is described by the differential equation:

Here, ( is specific density and g is the kxcal acceleration of gravity. For an ideal gas ( = MP/RT. where M is molar mass and R is the universal gas constant. Modeling the atmosphere as an isothermal column of ideal gas at 10oC, estimate the ambient pressure in Denver, where z = 1(mile) relative to sea level. For air, take M = 29 g mol-1; values of R are given in App. A.
