Reviewing particle size deposition results
Range of particle diameters
Two sizes chosen
Worst case scenario : 10μm
When measurable deposition begins : 4μm
12-10-13 Team 14054 22
Results Summary
ISO Standards : 2 s in between puffs
Tubing Design : 18 in of horizontal tubing
Settling Time Settling Length
10 μm 1.9 s 14.9 in
4 μm11.99 s 94.09 in
12-10-13 Team 14054 23
Conclusion
10 μm particles would have a chance to settle 4 μm particles would not have a chance to settle Negligible deposition of particles larger than 3.2 μm Most deposition occurs in particles ranging from 1μm to
0.18 μm
Negligible particle loss due to sedimentation

System flow resistance should be minimized Pressure drop of flow path shall not exceed 300 Pa
at a test flow rate of 17.5 mL/s. Dirty filter system should not exceed a pressure
drop of more than 250 Pa across.

The check valve with the lowest cracking pressure was found to be .17 psi = 1,172 Pa.
Component pressure drop ranges: 400 – 4,000 Pa.
Assessment: Simple check valve system will cause complications.

1. Clean air enters testing atmosphere via negative pressure from ventilation.
2. Clean air is drawn to fishtail chimney via negative pressure from sidestream flow (3 SLPM)
a. Air is drawn into tip of cigarette via mainstream negative pressure.
i. Oxygen in air is burned for fuel in cigarette.
ii. Air picks up various vapors are smoke particles. (Higher temperature).
iii. Air passes through cigarette butt. (Filters out some larger particles).
iv. Air passes through cigarette holder.
v. Air passes through one of the mainstream collection systems.
1. Collection filter collecting most of the particles. (Pressure drop and restricted flow).
2. Lung cast particle deposition setup consisting of:
a. Through humidification chamber adding moisture.
b. Through lung cast.
c. Exits through multiple exit points on lung cast into tubes.
d. Consolidates with the other flow paths in the collection chamber.
vi. Air passes through equipment protection filters. (Pressure drop and restricted flow).
vii. Air is drawn into syringe pump.
viii. Air is expelled from the syringe pump to exhaust flow path.

b. Air is continues up fishtail chimney via negative pressure from sidestream flow (3 SLPM)
i. Air mixes with sidestream smoke.
ii. Air converges into a tube.
iii. Air is filtered through main sidestream filter. (Pressure drop and restricted flow).
iv. Air passes through impinger to collect leftover particles. (Pressure drop, restricted flow, bubbling flow).
v. Air passes through secondary filters to “clean” air and protect equipment. (Pressure drop and restricted
flow).
vi. Air is drawn into sidestream pump
c. Air is expelled to ventilation.

Ideal gas law: P*V = n*R*T
Or: P = ρ*T*R/M
So: ρ = P*M/(R*T)
P = Absolute Pressure V = Volume R = Gas Constant T = Temperature ρ = Density M = Molar Mass
12-10-13 Team 14054 42
For steady state conditions: ṁ1 = ṁ2
Q1*ρ1 = Q2*ρ2
Q1 = Q2*ρ2/ρ1
From previous slide: ρ = P*M/(R*T)
