1. The art of being a good Chemical Engineer lies in being a good mathematician, a good chemist, and a good mechanic – all simul

taneously. All three of these are required for determining optimum economics. Generally speaking, we concern ourselves with operating costs (i.e. the chemistry side) and capital costs (i.e. the mechanical side). What can decrease operating expenses will, most likely, increase capital expenses. When designing equipment, we MUST be able to reconcile these two. The sweet spot is usually at the intersection of two curves (i.e. the mathematician side). Suppose that Operating Expenses could be expressed by the equation: y = 0.5x + 0.15, and Capital Expenses could be expressed by y = 1.25x2 + 0.1. To determine the minimal costs, you must find the point of intersection (assuming that only positive roots are applicable). (Solve analytically and graphically.) NOTE: When solving graphically, use graphing paper. 2. As you will learn in your chemistry courses and the reactor design course, the rate at which a chemical reaction proceeds is very much dependent upon the reaction temperature.

Answer:

y_{oe}=0.5x+0.15\\y_{ce}=1.25x^2+0.1\\\\

for minimum cost the intersection point should be calculated i-e

0.5x+0.15=1.25x^2+0.1\\\\1.25x^2-0.5x-0.5=0\\

By using calculator

x_1=0.4828\\x_2=-0.4828

As x can't be negative so x=0.4828

It's the minimum value because as we decrease the operating cost further the capital value will increase so this is the minimum value.

Salt Company is considering investing in a new facility to extract and produce salt. The facility will increase revenues by $220
e-lub [12.9K]

Answer:

12%

Explanation:

Annual net income:

= Increase in annual revenue - Increase in annual costs

= $220,000 - $160,000

= $60,000

Average investment:

= (Initial investment + Salvage value at the end) ÷ 2

= (980,000 + 20,000) ÷ 2

= $500,000

Annual rate of return:

= (Annual net income ÷ Average investment) × 100

= ($60,000 ÷ $500,000) × 100

= 12%

yuradex [85]

Answer: C. sensitive information

Explanation: A. precision

B. time for though

C. sensitive information

D. recall and memory decay

E. presumed knowledge

The instrument designer should be aware of errors arising from the issue of sensitive information when writing the target questions for the study. The issue of sensitive information deals with information that must be protected against unwanted disclosure and thus must be safeguarded usually because of legal, security or ethical reasons. It borders issues concerning personal privacy such as individual donor records, or those pertaining to proprietary considerations.

aksik [14]

Answer:

We will have $3227 at the end of 4 years.

Explanation:

In this case we are saving money each year starting with $650 in the first year, $670 in the second. $670 in the third and $830 in the last year which means the $650 saved in the first year will earn interest for 4 years, $670 for 3 years , then $670 for 2 years and $830 for 1 year. Now we have to find out the ending amount of each payment and add them up.

Future Value = Present value*(1+Interest rate)^Number of years.

FV 1st year savings=650*(1.0570)^4=811

FV 2nd year savings= 670*(1.0570)^3=791

FV 3rd year savings = 670*(1.0570)^2=748

FV 4th year savings= 830*(1.0570)^1=877

Add them all up to find how much will we have at the end of four years

=$3227
