From this I want to calculate the mass flow rate namely the product of the volumetric flow rate and the density. However the density is function of the pressure. Is it right the use the mean pressure of the input and output pressure in order to calculate the density of air?

air density The mass per unit of volume of air in terms of weight per unit of volume. The unit for measurement is kilogram per cubic meter (i.e., kg/m3). The illustration shows the values of air density in a standard atmosphere at various altitudes. ...
Calculate the Density of Air If you need to calculate the density of dry air, you canapply the ideal gas law. This law expresses density as a function of temperature and pressure. Like all gas laws, it is an approximation where real gases are concerned but is very good at low (ordinary...
