A flow process starts at Station 1 and then goes to Station 2. After station 2, 40% of the flow units to Station 3. Another 35% of the flow units leave Station 2 and go to Station 4. The remaining flow units go to Station 5. Flow units leaving Stations 3 and 4 exit immediately, but 20% of flow units leaving station 5 go to Station 4 while the remaining flow units go to Station 6 and then exit. The process does 16 jobs an hour.

 The processing time at Station 1 is 15 minutes. There is an average of 2.30 flow units waiting in front of Station 1 The processing time at Station 2 is 9 minutes. There is an average of 0.90 flow units waiting in front of Station 2 The processing time at Station 3 is 11 minutes. 

There is an average of 0.75 flow units waiting in front of Station 3 The processing time at Station 4 is 8 minutes. There is an average of 0.90 flow units waiting in front of Station 4 The processing time at Station 5 is 7 minutes. There is an average of 1.50 flow units waiting in front of Station 5 The processing time at Station 6 is 3 minutes. There is an average of 0.20 flow units waiting in front of Station 6
