(Equation 9)
(US Units)
or
(Metric Units)
Where:
= Low temperature correction factor
= Degrees Fahrenheit (Celsius) below 0°F (-18°C)
The temperature compensation factor, if required, must be added to the basic quantity of agent
calculated from the volume factors, and to all of the additional quantities calculated using
material conversion factors, leakage equations or curves, and ventilation formulas. The
additional carbon dioxide required to compensate for temperature shall be combined with the
basic concentration quantity.
(Equation 10)
Where:
= Quantity of agent to compensate for extreme temperatures, lb. (kg)
= High or Low temperature correction factor from Equation (8) or (9),
whichever factor is greater
= Quantity of agent for given concentration from Equation (2) or Equation
(12), lb. (kg)
= Quantity of agent to compensate for uncloseable openings from Equation
(6), lb. (kg)
= Quantity of agent to compensate for forced ventilation from Equation
(7), lb. (kg)
