PROCES SAFETY

A drum holds $1000$ kilogram of chemical at $25C$ and $1$atm. Using the given data at

Table $1,$ find:

a$.$ the size of the instantaneous cloud

b$.$ distance of virtual source, a$,$ and distance to lower flammable limit

c$.$ the concentration at site boundary.

d$.$ the distance of virtual source, $b,$ and distance to lower flammable limit for off$-$

site conditions.
