Question

1. a block flow diagram (bfd) shows: a) exact measurements and data b) the big picture of a process c) only final products d) energy balances 10. in soda bottling, which of these is an output? a) water b) syrup c) bottled soda d) carbon dioxide 11. what do arrows represent on a bfd? a) safety standards b) movement of materials c) yield percentage d) off - spec losses 12. why are bfds useful early in process design? a) they track energy balances b) they give a big - picture overview c) they guarantee high yield d) they prevent off - spec products 13. if yield is too low, a company may face: a) better profits b) increased waste and lost efficiency c) higher throughput d) improved reputation 14. which could cause a product to be off - spec? a) equipment failure b) extra throughput c) accurate diagrams d) high yield 15. the main purpose of a bfd is to: a) show every detail of equipment b) provide a big - picture view of processes c) perform chemical reactions d) calculate missing mass

Explanation:

1. A block - flow diagram (BFD) gives an overview of a process, not exact measurements, final products only, or energy balances.
2. In soda bottling, bottled soda is the output. Water and syrup are inputs, and carbon - dioxide is used in the process but not the main output.
3. Arrows on a BFD represent the movement of materials.
4. BFDs are useful early in process design as they give a big - picture overview. They don't track energy balances, guarantee high yield, or prevent off - spec products at this stage.
5. Low yield leads to increased waste and lost efficiency, not better profits, higher throughput, or improved reputation.
6. Equipment failure can cause a product to be off - spec. Extra throughput, accurate diagrams, and high yield don't typically cause off - spec products.
7. The main purpose of a BFD is to provide a big - picture view of processes, not show equipment details, perform chemical reactions, or calculate missing mass.

Answer:

1. b) The big picture of a process
2. c) Bottled soda
3. b) Movement of materials
4. b) They give a big - picture overview
5. b) Increased waste and lost efficiency
6. a) Equipment failure
7. b) Provide a big - picture view of processes
