In this article let me help you on air density calculator. The application of knowledge of density of air at STP and various temperature is important for various disciplines in science.density of air can be defined as the mass of the dry or humid air per unit volume.
Introduction to density of air at stp
Density of the air depends on various factors like the temperature, altitude, pressure as well as the presence of humidity. here i am giving the method of calculating the density of the dry air at STP.
The STP conditions are 273K and 1 atmospheric pressure or 101325.03 pascal , to calculate the density in Kg/m^3, the universal or molar gas constant (R) has to be converted in to specific gas constant.
The molar mass of the dry air =28.97 g. This could also help us on logarithm table
The specific gas constant = R / 28.97J g-1K-1
= 8.314 / 28.97J g-1K-1
= .28698 Jg-1K-1
= 286.98 JKg-1 K-1 (JOULES PER Kg PER KELVIN)
