Question

Cost of instrumentation in a modern chemical plant as compared to the total plant cost, ranges from:

• A. 1.5 to 10%
• B. 20 to 30%
• C. 40 to 50%
• D. 60 to 70%

Hint:

The cost of instrumentation is a small but important part of the overall plant cost, typically between 1.5% and 10%.

Answer 1

The Correct Option is A

Step 1: Understanding instrumentation costs.
In a modern chemical plant, the cost of instrumentation is generally a small portion of the total plant cost, typically ranging from 1.5% to 10% of the total cost.

Step 2: Explanation of options.
- (A) 1.5 to 10% is the typical range for instrumentation costs. - (B), (C), and (D) These values are too high for instrumentation costs, as they do not exceed 10% in a typical plant.

Final Answer: \[ \boxed{\text{A) 1.5 to 10%}} \]
