G-4. Building Number 2.
Building number 2 is a poured concrete structure with 0.66-m-thick walls and roof. The facility
has no windows. Leakage rate versus internal pressure is shown in Figure G-2. Building leakage
rates can be calculated using equation G-2.
log(y) = C0 + C1log(x)
(eq G-2)
where: C0 = 1.8871234
C1 = 0.54579516
y = leakage rate, L/s
x = internal pressure, Pa
