The amount of FM200 gas required can be calculated using the formula:

Weight of Gas=Net Volume×Design Concentration×S-Factor\text{Weight of Gas} = \text{Net Volume} \times \text{Design Concentration} \times \text{S-Factor}Weight of Gas=Net Volume×Design Concentration×S-Factor

Using metric units:

Net Volume: 2,500 m³

Design Concentration: 7% (or 0.07)

S-Factor: 0.1359

Calculation:

2,500 m3×0.07×0.1359=821.325 kg2,500 \, \text{m}^3 \times 0.07 \times 0.1359 = 821.325 \, \text{kg}2,500m3×0.07×0.1359=821.325kg

Rounded to the closest answer:820 kg

In imperial units:

Net Volume: 88,287 ft³

S-Factor: 1.885

Calculation:

88,287 ft3×0.07×1.885=1,165.27 lbs88,287 \, \text{ft}^3 \times 0.07 \times 1.885 = 1,165.27 \, \text{lbs}88,287ft3×0.07×1.885=1,165.27lbs

Rounded, this is approximately1,800 lbs.
