WebOct 11, 2024 · I'm trying to understand how one can calculate pressure, density and temperature of the atmosphere as a function of altitude. ... That seems incorrect though as density clearly does change with altitude. 4) It's not clear if I can obtain $\rho(z)$ from some other consideration independently. WebApr 1, 2024 · 1. Thanks! I think I see: thrust drops with decreasing altitude due to back pressure, and that drop reflects in the drop in specific impulse. So if you capture the change in one, you capture the change in the other, it seems---unless the specific impulse depends on still other variables not accounted for in the change in thrust. grapenuts expected store shelves

WebJan 12, 2016 · At the cruise altitude of the Concorde the atmospheric temperature is below that of the standard atmospheric temperature at sea level, so the speed of sound is also lower. That is the simple answer. WebChange in the Atmosphere with Altitude Air pressure changes with altitude. Air is all around us, but we cannot see it. Gravity from the Earth pulls air down - this is called air pressure. We don't feel this pressure because our bodies push an equal amount of pressure outward.
