"A student decides to compute the standard barometric reading on top of Mt. Everest (29,028ft) by assuming the density of air has the same constant density as the sea level. Try this yourself. What does the result tell you?" Am I doing this right? h = 8847.7344 m density of air = 1.29kg/m3 pressure = density * g * h = 111.853 kPa Since the by using constant density, we see that the pressure is higher on Mt. Everest. Of course, we know this to be false. Therefore, the density of air must be less on Mt. Everest than at sea level. I'm not sure this is right, but please check.
