P/N 81-CO2MAN-001 3-81 September 2013
Note that the equivalent lengths of hoses are given for 50-foot (15.24-meter) lengths of hose.
As the actual hose length may vary from 25 ft. to 200 ft. (7.62 m to 60.96 m), the equivalent
length for the system hose may be calculated from Equation (36).
(Equation 36)
(US Units)
or
(Metric Units)
Where:
= Equivalent length of hose, ft. (m)
= Equivalent length of 50 ft. (15.24 m) hose from Table 3-14 and 
Table 3-15
= Actual length of hose, ft. (m)
3-16.4.2 MINIMUM AGENT QUANTITY
A hand hose line system is a local application of agent, and therefore only the liquid portion of
the discharge is effective. A vaporization factor of 40% must be applied to the total agent
quantity to be supplied.
(Equation 37)
Where:
= Minimum quantity of agent to be supplied, lb. (kg)
= Nominal system flow rate from hydraulic calculation, lb./min.
(kg/min.)
= Duration of discharge, minimum 1 min.
