(Equation 24)
Where:
= Number of nozzles per row
= Length of protected area, ft. (m)
=Maximum length of nozzle coverage area from Equation (23) up to 5 ft.
(1.52 m), ft. (m)
(Equation 25)
Where:
= Length of nozzle coverage area, ft. (m)
= Length of protected area, ft. (m)
= from Equation (24) rounded up to the next whole number
(Equation 26)
Where:
= Actual nozzle coverage area,
ft.

)
= Width of nozzle coverage area from Equation (22), ft. (m)
= Length of nozzle coverage area from Equation (25), ft. (m)
(Equation 27)
Where:
= Quantity of nozzles
= from Equation (21) rounded up to the next whole number
= from Equation (24) rounded up to the next whole number
The total discharge rate for tankside nozzle protection may be calculated using Equation 28.
(Equation 28)
Where:
= Total discharge rate for tankside nozzle protection, lb./min (kg/min)
= Single nozzle discharge rate from Table 3-7 or Table 3-8, lb./min (kg/min)
= Actual nozzle coverage area from Equation (26),
