Question

process technology review worksheet (mo version) name: date: passage 1 - the big picture: from inputs to outputs in process technology, a process is a series of steps that transforms raw materials into a sale and settable product. these raw materials are called feedstock once they enter the system. for example, crude oil is feedstock in refineries, while wood chips are feedstock in paper mills. technicians track two important measures: throughput and yield. throughput is the amount of material processed in each time. for instance, a refinery may have a throughput of 10,000 barrels of crude oil per day. yield measures the percentage of feedstock that becomes finished product. if 100 pounds of feedstock enter a system and 85 pounds of usable product leaves, the yield is 85%. high yield means less waste and more profit. sometimes, products are off - spec (off - specification), meaning they do not meet quality standards. off - spec products may be unsafe, unreliable, or costly to reprocess. a company producing off - spec material risks losing money and damaging its reputation. to help technicians visualize these steps, engineers use block flow diagrams (bfds). these diagrams are simple rectangles connected by arrows that show how feedstock moves through transformations to outputs. for example, in soda bottling, inputs include water, syrup, and carbon dioxide. steps include filtering, mixing, carbonating, bottling, and sealing. the outputs are bottled soda and waste streams such as spilled syrup or excess gas. by studying the big picture with bfds, technicians can spot where problems may occur, improve efficiency, and maintain safety throughout the process. multiple - choice questions for passage 1 1. feedstock is best defined as: a) finished product b) raw material entering a process c) waste from a process d) a type of diagram

Explanation:

The passage states "These raw materials are called feedstock once they enter the system". So feedstock refers to raw materials entering a process.

Answer:

B. Raw material entering a process
