900 ft .....Elevation
110 F ....Temp
29.92 ....Barometer guess
90% ......Humidity
5,282 ft .....@ the Y.M.C.A.
(What?? That's where the steam room is. g)
Where does elevation come into it? temp, pressure and humidity defines the
density of the air ( 1.083kg/m3 in this case) , which is then compared to
the density of the standard atmosphere, which in my calcs gives 4140 ft as
the density altitude.
