Problem 1. (Modified from FRB 4th edition 4.12) 35 marks. Eggs are sorted into 2 sizes (large, and extra-large) at the Cheerful Chicken Coop Co-op. The automated sorting unit has failed, and the owner, Esmerelda Egghead has implemented a new work process until repairs can be completed. Ms. Poulet, one of the sharper-eyed employees, has been assigned the job of stamping each egg. The eggs pass her on a conveyer system. The large eggs are stamped " L " with a rubber stamp in her right hand. She stamps extra large eggs " XL, with a stamp in her left hand. In the process, she breaks 9% of the eggs. Down the line, the graded whole eggs are put into appropriate cartons for sale. The contents of the broken eggs are collected, and sold to industrial bakeries at a considerable discount to fresh whole eggs. 120 eggs per minute pass Ms. Poulet. On average, 65 eggs/minute are extra-large, and of these "XL" eggs, 8 are broken per minute. a) Draw and label a Block Flow Diagram for this process. b) Write and solve the balances for total eggs, and broken eggs. How did you manage part of an egg, if your solution doesn't work out evenly? c) How many large eggs leave the plant per minute, and what fraction of them are broken? d) Is Ms. Poulet right handed, or left handed? Justify your answer. e) Large eggs average 50g each, extra-large eggs weigh 70g each. What is the 'recovery' of high quality (unbroken) eggs in this process (by weight). f) Can you suggest a process that would produce much less breakage
