Webρ = density of fluid (1.2 kg/m 3 for air at NTP) v = flow velocity (m/s) A = characteristic frontal area of the body (m 2) The drag coefficient is a function of several parameters like shape of the body, Reynolds Number for the flow, Froude number, Mach Number and Roughness of the Surface. The characteristic frontal area - A - depends on the body. Webρ gas = density of gas [kg/m 3] ρ air = density of air (normally at NTP - 1.204 [kg/m 3 ]) NTP - Normal Temperature and Pressure - defined as 20 o C (293.15 K, 68 o F) and 1 atm ( 101.325 kN/m2, 101.325 kPa, 14.7 psia, 0 psig, 30 in Hg, 760 torr)

WebApr 6, 2024 · The S.I unit of density of air is kg/m3. Consider an air taken in a container of volume 1 m3, then the mass of the air inside that container having volume 1 m3 is equal to the density of air.There are some factors that the density of air depends upon. Variation of Density of Air at Different Altitudes WebAt sea level and at 15 °C, air has a density of approximately 1.225 kg/m3 (0.001225 g/cm3, 0.0023769 slug/ft3, 0.0765 lbm/ft3) according to ISA (International Standard Atmosphere).
