SpletThe density of air or atmospheric density, denoted ρ, is the mass per unit volume of Earth's atmosphere.Air density, like air pressure, decreases with increasing altitude. It also changes with variation in atmospheric pressure, temperature and humidity.At 101.325 kPa (abs) and 20 °C (68 °F), air has a density of approximately 1.204 kg/m 3 (0.0752 lb/cu ft), according …
SpletSo if I want to calculate density of wind at a high altitude, where pressure and temperature are lower, I use: rho = P/RT where P is either total or static pressure, R = 287 J/kg-K, T = total or static temperature (K). Also, when we say that standard atmospheric pressure is 101,325 Pascals, is this standard pressure static or total? SpletThe formula for P (t) is one of the Important Formulas The formula, once again, is P (t) = P (0)* e^rt. Now we need to fill in all the blanks we can. Our P (0) is given to us in the problem to be equal to 3. Our r is also given to us in the problem to be .02 because the other Important Formula is P' (t) = r * P (t).
