In an isothermal atmosphere the pressure
WebWith this definition of H, the density in an isothermal atmosphere ... (11) we see that the air density (and pressure) at the summit will be exp(−8.85/H) = exp(−1.05) = 0.35 times that at sea level. Humans can only survive at pressures below half an atmosphere for short periods of time. 2. Hydrostatic Equilibrium in Isothermal Thin Disks WebFour pounds of air gain 0.491 Btu/R of entropy during a nonflow isothermal process.
