: FM 200 Fire Extinguishing System Protection and hydraulic calculations for Qtel Room is in accordance with NFPA 2001 (2004 Edition)

Amount of Clean Agent Required to Achieve Design ConcentrationW = (V / S) x (C / (100-C)) NFPA 2001, 5.5.1 Total Flooding Qty. Equation (3.1)Where:

W

= weight of clean agent, (kg)

V

= net volume of hazard, (m)

S

= specific volume of the superheated agent vapour at 1 atmosphere and the

temperature, T (m/kg)

C

= agent design concentration (volume percent)T

= minimum anticipated temperature of the protected volume (C)

Design Data:

Volume of Hazard

: 196m

Extinguishing Agent

: HFC-227ea

Design Concentration

: 7%

Design Temperature

: 20C

Specific Volume of the Superheated: 0.1376 m/kg (NFPA 2001, Table A.5.5.1(k)

Agent Vapour at Design Temp and 1 Atm. Thus:

W= (V / S) x (C / (100-C))

= (196 / 0.1376) x (7 / (100-7))

W= 107 kg Fire Fighting
