RATE OF SPREAD (ft/min) 



Figure 5. — Frequency distribution of the rate of spread in slash fuels at wind- 

 speed and at a 2 mi/h_ winds-peed. The average rate of spread is indicated for 

 the uniform model (average fuel parameters from t/ze simulated array) for com- 

 parison with the nonuniform model (average valve of the distribution) .
