A volcano has erupted, spewing stones, steam, and ash several thousand meters into the atmosphere. After some time, the particles begin to settle to the ground. Consider a nearly spherical ash particle of diameter 50 µm, falling in air whose temperature is −50°C and whose pressure is 55 kPa. The density of the particle is 1240 kg/m3. Estimate the terminal velocity of this particle at this altitude.

explain the effect of aerodynamic drag and lift on aerofoils
A propeller-driven aircraft has an in-flight weight of 4,105 lb (equivalent to a mass of 1,862 kg) and is cruising at a true airspeed of 120 kts. The lift-to-drag ratio of the aircraft is 8.2. If the propeller efficiency, ηp, is 0.8, then how much brake power is required for flight? Work through this problem in both USC and SI units.
