Skill D2. Consider a workstation that finishes small metal parts in a barrel burnishing machine that processes multiple parts at the same time by tumbling.  The mean processing time equals 5 minutes (for a batch), and the processing time standard deviation is 2 minutes.  The machine can hold up to 100 parts. What is the capacity (parts per hour) of this machine if the batch size is 50 parts?

Skill D5.   Consider this board production line that has the following characteristics (data from Hopp and Spearman).  Parts arrive at a rate of 36 boards per hour, and the SCV of the interarrival times = 1.  Suppose that boards are moved in transfer batches of 40 boards from the MMOD workstation to the SIP workstation.  Estimate the total cycle time (in minutes) for these two workstations.                                                                Number of          Mean process               Process time                          Workstation                   machines           time (minutes)                    SCV                              MMOD                             1                          1.43                                4                                 SIP                                1                          1.43                                4

Consider the reaction between HCl and O2: 4HCl(g)+O2(g)→2H2O(l)+2Cl2(g) When 63.1 g of HCl is allowed to react with 17.2 g of O2, 46.0 g of Cl2 is collected. You may want to reference (Pages 260 – 264 (Links to an external site.)) Section 8.6 while completing this problem. Determine the percent yield of this reaction. Express your answer as a chemical formula.
