3-) A heat exchanger with 1 body - 4 pipe passages and each pipe (100+ ??) (with a diameter of 2.6 cm each, 4 m long thin wall per pass) will be used to heat the air. Water enters the pipes with a mass flow of 8 kg / s at 350 K temperature, and air enters the body at a temperature of 15 C with a mass flow of 18 kg / s. The pollution factor of the sediment formed inside the pipe over time is 0.0026 m'K / W. Transport coefficients on the inner and outer surfaces of the pipes are estimated at 450 and 200 W / m'K, respectively. Using specific temperatures at 25 ° C for air and water (?? = school no. Last two digits, for example 0611002072; ?? = 72, ie 172 units), a-) the efficiency of the heat exchanger by drawing the shape of the problem, b-) Heat transfer rate ( kW), c-) Calculate the outlet temperatures (C) of the water and air and show the temperatures in the T_L diagram.

Prepare an income statement using Absorption Cost and other using Variable costs.

D's company produce donuts.

The variable cost of making each box of donuts is $ 0.40.
The Fixed Production Costs are $ 65,000.
Administrative and variable sales expenses are $ 0.20 per box.
The administrative and sales Fixed Costs are $ 55,000.

During 2018 the company produces 500,000 and sells 450,000 boxes of donuts to $ 1. The company has the capacity to produce 600,000 boxes of donuts. The company uses a calendar year and this is its first year of operations.

1. Prepare the Income Statement for full costs (absorption cost) and for variable costs. There is no tax rate.

2. A school wishes to raise funds for the graduating class. They extend an offer to buy 5,000 boxes per month for 10 months at $ 0.60. If the company accepts, this sale will not affect normal sales. The company must incur all variable costs, but not fixed costs. Determine if you accept the offer or reject it. Present your computations.

When you stick ice in a drink, AFAICT (the last physics I took was in high school) two things cool the drink:

• The ice, being cooler than the drink, gets heat transferred to it from the drink (Newton's law of cooling). (This continues after it melts, too.)
• The ice melts, and the cool liquid mixes with the drink, which makes the mixture feel cooler.

My first question is, to what extent does each of these cool the drink: which has a greater effect, and how much greater?

Secondly, how much of the cooling by the first method (heat transfer) is without melting the ice? That is, is there any significant amount of heat transfer to each speck of ice before it's melted, and how much does that cumulatively affect the drink's temperature?

I suppose all this will depend on a bunch of variables, like the shape and number of ice cubes and various temperatures and volumes. But any light that can be shed, let's say for "typical" situations, would be appreciated.

a) We all talk about media effects, how what we read, see, listen to has an impact on our lives, whether it's as simple as getting a weather alert and making decisions about how we're going to dress that day to having news stories shape our opinions about politics. Media may also affect how we perceive the world and our attitude about violence, sex, drugs and stereotypes, to name a few.

What kind of impact do you believe media has on you and others and our attitudes about those things?  Do you think the media is directly responsible for those attitudes people have? What about for people's actual actions (such as school shootings)?

b) Whether you're reading a newspaper or posting something on Instagram or watching something on Netflix, how much time do you spend with media? Is it surprising? Are you even doing it in your sleep?

Mary Martin, a female, tenured teacher in a rural conservative district, was stopped by the local police and charged with driving under the influence. She explained to the police that she had just left a Christmas party given by her principal and that she had consumed only a few glasses of wine. She was also aware that some of her male colleagues had been stopped in the past but not charged. Nevertheless, she was still charged. As her arrest becomes public, there is pressure from the school board for her to resign.

Discussion Questions

1. Can the board force Martin to resign? Why or why not?
2. Is the infraction serious enough to warrant dismissal? Why or why not?
3. What about male colleagues who were not charged for similar offenses?
4. What rights does Martin have as a teacher in this situation?
5. What factors would the court consider in ruling on her case?
6. What conclusion do you think the court would reach in this situation? Provide a rationale for your response

Spruce Street Shelter Sam Donaldson, the laundry supervisor of the Spruce Street Shelter, stared at the memo that had just reached his desk: The shelter has adopted a responsibility accounting system. From now on you will receive quarterly re- ports comparing the costs of operating your department with budgeted costs. The reports will highlight the differences (variances) so that you can zero in on the departure from budgeted costs. (This is called management by exception.) Responsibility accounting means you are accountable for keeping the costs in your department within the budget. The variances from the budget will help you identify which costs are out of line, and the sizes of the variances will indicate the most important ones. Your first such report ac- companies this announcement. [Exhibit 1] As this report indicates, your costs are significantly above budget for the quarter. You need to pay par- ticular attention to labor, supplies, and maintenance. Please get back to me by the end of this week with a plan for making the needed reductions. Mr. Donaldson knew he needed a plan, yet midwinter was the busiest time of the year at the shelter, and the laundry was piling up faster than his staff could wash it. BACKGROUND Spruce Street Shelter was located in the heart of a large metropolitan area in the north-central United States. Founded in the late 1800s, it had been serving the homeless ever since, providing hot meals, shelter, and companionship. Situated on a busy urban thoroughfare, it was a haven of last re- sort for many of the city's indigent, and “home” for many others. As might be expected, the de- mand for its services was especially high in the winter, when temperatures frequently dropped to below freezing, and life “on the street” became unbearable. The shelter provided three services. Its most significant activity was the Hot-Meal Program, where it served hundreds of meals a day. A meal of hot soup and a sandwich was available to any- one who arrived between the hours of noon and 2pm and 5pm to 7pm. Its second program was its Overnight Hostel, where it had 150 beds that were available on a first-come, first-served basis. The linen was changed daily, and fresh towels were always available, so that the shelter’s clients could look forward to “clean sheets and a hot shower.” Finally, it had a counseling program, in which a staff of three full-time social workers assisted clients to cope with the difficulties that had brought them to the shelter, and in establishing themselves in a more self-sufficient lifestyle. SYSTEM CHANGES In March, the shelter had hired a new administrator to improve its business activities. A busi- ness school graduate with prior experience in manufacturing and service companies in the private sector, one of his first steps had been to introduce what he called “responsibility accounting.” He had instituted a new budgeting system, along with the provision of quarterly cost reports to the shelter’s department heads. (Previously, cost data had been presented to department heads only in- frequently.) The annual budget for the current fiscal year had been constructed by the new administrator, based on an analysis of the prior three years’ costs. The analysis showed that all costs increased each year, with more rapid increases between the second and third year. He considered establishing the budget at an average of the prior three years' costs hoping that the installation of the system would reduce costs to this level. However, in view of the rapidly increasing prices, he finally chose HBSP Product Number TCG267 THE CRIMSON PRESS CURRICULUM CENTER THE CRIMSON GROUP, INC. _____________________________________________________________________________________________ This case was prepared by Professor David W.

He decided to measure ac- tivity by client nights, and to set the budget for pounds of laundry processed at last year’s level, which was approximately equal to the volume of each of the past three years. Quarterly budgets were computed as one-fourth of the annual budget. Mr. Donaldson had re- ceived the report shown in Exhibit 1 in mid-January. He reflected on its content: A lot of my costs don’t change, even if the number of pounds of laundry changes. I suppose laundry la- bor, supplies, water-related items, and maintenance vary with changes in pounds, but that’s about all. Nevertheless, shouldn’t my budget reflect those changes? Also, I hadn’t planned for the fact that I was given a salary increase as of October 1—was I supposed to refuse it to help keep my budget in balance? Finally, I think it’s important to note that I had to pay overtime to the staff because the department became inundated with laundry during the cold snap we had back in mid-December. Because of this, my average hourly rate for the whole three months was $10.20 instead of the $9.00 that was in my budget. In fact, and maybe this is a little picky, the average number of minutes it took my staff to wash a pound of laundry actually dropped from .48, which was my budget target, to .47 for the quarter. Somehow, even though it’s pretty small, I think that should be taken into consideration.
