Answer:
the average flow (vph) = 222.69 veh/hr.
The average velocity = 111348 ft/hr.
density = 2 × 10⁻³ veh/ft.
Explanation:
The first thing to do in this particular question is to determine the average velocity.
The average velocity = [ ( 2940 - 2000/30) + ( 3200 - 2300/30) + ( 2400 - 1700/30) + ( 2100 - 1200) + ( 1730 - 600/30) + ( 1000 - 0/30).
The average velocity = [31.33 + 30 + 23.33 + 30 + 37.66 + 33.66]/ 6 = 30.99 ft/sec.
Thus, 30.99 ft/sec × 60 × 60 = 111348 ft/hr.
The next thing to do is to determine the density. therefore, the density = 6/ 3000 = 2 × 10⁻³ veh/ft.
The average flow (vph) = 111348 ft/hr × 2 × 10⁻³ veh/ft. = 222.69 veh/ hr.
Also, the space mean speed (mph) over the 3000 ft length of the lane = 6/ [ 1/31.33 + 1/30 + 1/23.33 + 1/30 + 1/37.66 + 1/33.66] = 6/ 0.1977 = 30.34 ft/sec.
Extractive industry, can be defined as a processes that involve different activities that lead to the extraction of raw materials from the earth (such as oil, metals, mineral and aggregates), processing and utilization by consumers.
Answer: Manufacturing engineers may be responsible for solving production problems, conducting cost-benefit assessments, or designing and manufacturing goods and systems using computer-aided design software. Plant engineers and process engineers are two terms used by professionals in this industry. Manufacturing engineers are in charge of new and existing production lines' technical management, maintenance, and development. Employers are looking for people that are commercially aware and have good technical and analytical skills. They are in charge of keeping production costs low while preserving the product or service's quality, and they have considerable project expertise and insight.
Explanation: See above.
I hope this helps.
Huh , what last question JSJS XD
