Characteristic diameter (dc) of the nasal cavity calculated via equation (8) and length from the nostrils to the end of the septum (Lnose). The nasal resistance (Rnose) was calculated fitting the pressure drop versus flow rate data with Δp = RnoseQ1.75. r2 is the correlation coefficient of the fitting.
