Eggs are sorted into sizes (large and extra large) at the cheerful chicken dairy. Unfortunately, buss has not been good lately, and since the Cheerful Chicken's 40-yr-old eggs sorting machinery finally gave up the ghost there have been no funds available to replace to replace it. Instead, old Fred, one of the Firm's-eyed employees, has been equipped with a "large" rubber stamp in his right and an "X-large" stamp in his left, and assigned to stamp each egg with the appropriate label as it goes by on the conveyor belt. Down the line, another employee puts the eggs into one of two hoppers, each egg according to its stamp. The system works reasonably well, all things considered, except that Old Fred has a heavy hand on the average breaks 30% of the 120 eggs that pass by him each minute. At the same time a check of the "X-large" stream reveals a flow rate of 70 eggs/ min, of which 25 eggs/min are broken.
(a) Draw and label a flow chart for this process.
(b) Write and solve balances about the eggs sorter on total eggs and broken eggs
(c) How many "large" eggs leave the plant each minute?
(d) What fraction of the "large eggs are broken?
(e) Is old Fred right or left handed?
