Problem 1: A wastewater is treated in an aerobic CSTR with no recycle. Determine θx min, [θxmin]lim , Smin if the following parameters hold: K= 50mg/l, q^ = 5 mg/mg VSSa-d, b=0.06/d, Y= 0.60 g VSSa/g, So= 220mg/l, and Fd = 1.0 or 0.8 ( two answer ).                            

A thin-walled pressure vessel is constructed by bending a 0.5 cm thick plate into a cylindrical shape. A curved plate is bolted over the gap as shown. The 1 cm diameter bolts are spaced 3 cm apart. The bolt metal shear strength is 30 MPa. What pressure can the vessel hold before the bolts shear? Assume no bending and no stress concentration at connections.

A project requires use of spare computer capacity. If the project is not terminated, the company will need to buy an additional disk at the end of year 2. If it is terminated, the disk will not be required until the end of year 4. Disks cost $10,000 and last 5 years. The opportunity cost of capital is 10% (an annual rate compounded annually).

a) What is the present value of the cost of this extra usage if the project continues indefinitely?

b) What if the project is terminated at the end of year 2?

You lead a product development team for a company that produces training materials. The team has been working together for about six months to produce a new frontline leadership training program. The team consists of the following individuals, who all report to you:

Judy Sachs, an instructional designer. Judy has been a designer for many years, and with this company for about five. She knows the business inside and out.

Jeremy Links, a writer. Jeremy has a degree in writing but has not conducted training. He has been with this company for a little over a year and this is his second project.

Sheila Lombardo, a writer. Sheila has been writing training materials for about three years and has been a professional writer for about ten years. She has a reputation for being highly efficient and an excellent writer and producer of materials.

Jennifer Snow, a media developer. Jennifer has been with the company for three years, and has ten years of experience developing video, online, and Powerpoint media support for training programs.

The team was originally committed to a deadline that they – and you – were skeptical they could meet. The people in sales were anxious to get the product to market so they could head off a competitor’s new product. Now, as the deadline is approaching, the team is behind schedule. Judy has said openly that if the writers were more experienced at writing training, things would go faster. All four of them are angry for agreeing to an unrealistic deadline in the first place. Jennifer has said that she can’t do her job until Judy, Jeremy, and Sheila do theirs. So, she’ll have to work nights and weekends, and she’s not very happy about that. Sheila and Jeremy both keep working away at their computers without saying much to anyone. In the parking lot one evening, Jeremy said to Sheila, “I think they’re expecting miracles from us. Did you know that Judy has rewritten most of what you and I have done? No wonder it’s taking so long.” Sheila replied, “That witch! I asked her directly if she was reviewing anything we did, and she said ‘no’!” Does our manager know she’s doing this?” “I don’t know,” Jeremy answered, “but I just feel like there’s no way for me to win here – you either. It’s a set-up.”

write a 900-1200 word analysis of this situation, making sure to address the following questions. (Don’t just answer the questions, write the analysis.)

-Which type(s) of conflict is/are most evident here?

- What should you (the manager) do to make this conflict more productive?

- Which approach of the five approaches given in the lecture would be most appropriate for you to use here and why?

- Which approaches should the others use and why?

- If you leave this team alone to work things out for themselves, what is likely to be the result?

Rosser Company produces a container that requires 4 yds. of material per unit. The standard price of one yard of material is $4.50. During the month, 9,500 chairs were manufactured, using 37,300 yards. Required: Journalize the entry to record the standard direct materials used in production.
