Explanation:
1. Circumference is pi times diameter.
C = πd
C = 9π inches
C ≈ 28.3 inches
2. Mechanical advantage is ratio of output force to input force.
MA = Fout / Fin
MA = 155 lb / 15 lb
MA ≈ 10.3
3. Mechanical advantage is ratio of input distance over output distance.
MA = din / dout
MA = 10.5 in / 0.85 in
MA ≈ 12.4
4. Mechanical advantage of pulley system is the number of strands.
MA = 8
5. Mechanical advantage is ratio of output force to input force.
MA = Fout / Fin
8 = Fout / 200 lb
Fout = 1600 lb

Answer:
Explanation:
The diffusion coefficient is computed by using this Arrhenius-type Model:
The following is constructed by dividing to two distinct diffusion coefficients:
Any diffusion coefficient at a different temperature can be found by using this formula:
Answer:
Explained
Explanation:
Oxygen tank = Oxygen enriched air tank
Hydro static pressure increases with the depth, generally around 1 bar for 10 meters of depth. This high pressure condition leads to increasing in the partial pressure of oxygen in the scuba tank. This leads to a condition called oxygen toxicity. It causes when breathing molecular oxygen at higher partial pressures. It leads to cell damage in the nervous system, lungs, and eyes. So, while designing such gear we have to be careful that oxygen partial pressure shouldn't exceed certain pressure.
