I'm trying to solve a differential equation problem that has to do with barometric pressure at a certain altitude.
The rate at which barometric pressure decreases with altitude is proportional to the pressure at that altitude. If the altitude in feet, then the constant of proportionality is 3.7 x 105. The barometric pressure at sea level is 29.92 inches of mercury.
How would I calculate the barometric pressure, in inches of mercury, at any altitude using the information above?
The differential equation that I came up with looks like this:
Let $P=$ Barometric Pressure
Let $a=$ Altitude
But when I solve it, it doesn't look like it's the right answer.
Thanks for your help!
