The sprinkler files contained in this directory have been 
contributed by Dave Sheppard who generated them as part of
his doctoral studies at Northwestern University. The naming
convention is based on English units. For example, the
file called pk03_32.spk contains properties of a pendant  
sprinkler with K-Factor (gpm/psi^0.5) equal to 3, and 
pressure set at 32 psi.
