1.16 The trachea has a diameter of 18 mm; air flows through it at a linear velocityof 80 cm/s. Each small bronchus has a diameter of 1.3 mm; air flows throughthe small bronchi at a linear velocity of 15 cm/s. Calculate the volumetric flowrate, mass flow rate, and molar flow rate of air through each of these regionsof the respiratory system. Also, calculate the Reynolds number for each com-partment, given the formula:DvpRewhere D is diameter, v is linear velocity, p is density, and pu is viscosity. Theviscosity of air is 1.84 × 10 g/(cm• s).

Given: d=18 mm =1.8 cm v=80 cm/s

Answered: of 80 cm/s. Each small bronchus has a…

Exercise 2: Ventilation Requirements. In order to calculate the quantity of ventilation air needed for habitation, we need considering: V The CO, production P m3/s, and for this example, of a sedentary adult. V The concentration Cs% of CO,% in outdoor air, and V The maximum threshold CO, concentration Cr% for the occupied space. Normally, P = 4.7x10-6 m³/s per person, Cs =0.03% and Cr =0.5%. %3D If the flow rate, Q m³/s is the rate of fresh air flowing through a room to provide acceptable conditions, a CO, balance can be made.
