Notes: 1. The design water demand should be 8 + 8 + 16 + 16 =
48 L/s for the occasional times when two 64 mm and
two 38.1 mm cooling water hoses are used together.
This is the total demand for the structure. Do not
add in the water for foam.
2. The maximum 3 percent foam solution demand should be
16 + 16 = 32 L/s.

Notes: 1. The water category includes the water portion of the
AFFF (97 percent water, 3 percent AFFF for design)
and the flush deck nozzle water.
2. 46 percent of the water usage for a 2-day class occurs
occurs on the first day of class. However, since the
whole course is taught in one day to the accelerated
students, the design daily water consumption equals
the full class value.
