2. A refrigeration machine has been designed based on R134a. The design capacity is 15 tons.   The evaporator coil design temperature is 8 oC. The refrigerant enters the compressor as a slightly superheated vapor at 15 oC. The condenser coil design pressure is 14 bar. Refrigerant enters the expansion valve as a compressed (subcooled) liquid at 44 C. Note that the temperature of the air passing over the tubing in the evaporator coil will be higher than 8 oC and the temperature of the air passing over the condenser coil will be lower than the coil temperature. Use 80% for the compressor isentropic efficiency.
a. Calculate the power required to run the compressor under these design conditions and the required mass flow rate of R134a. (30 pts)

b. Find the rate of heat transfer for the condenser (high pressure side) of the system. (15 pts)

c. Find the quality of the refrigerant as it enters the evaporator. (10 pts)



3. A small gas turbine engine is used to produce power for auxiliary systems. This is a simple gas turbine open to the atmosphere. Air enters the compressor at 1 bar, 300 K. The compressor pressure ratio is 3.5:1. After passing through the combustion chamber, the air enters the turbine at a temperature of 1300 K. Determine the mass flow rate of air needed for the turbine to produce 60 kW of power. Also determine the heat that must be generated in the combustors. (30 pts) Solar collector …

Nihonno Tsukuruno, Inc. uses the FIFO method of process costing. The firm has only one production department. It has the following cost per equivalent unit rates for the month of January. $12.50 direct materials per equivalent unit $17.25 conversion costs per equivalent unit Here are some additional details about the firm. The firm began the period (i.e. January 1) with $10,000 of direct materials cost and $15,000 of conversion costs in beginning WIP. Those beginning WIP costs were incurred for 1,000 beginning WIP units that were 50% complete with respect to conversion costs and direct materials. The firm completed and transferred out a total of 59,000 units in January. What is the cost of units completed and transferred out for January (including direct materials costs and conversion costs)?

1. An important principle of change management is:

   		Make sure that DEV, QA, and PRD are set up technically correct
   		Have a data collection, standardization, and harmonization plan in place
   		Involve only top management
   		Educate users during planning for ERP on the system's benefits

1. All of the following are benefits of activity-based costing except:

   		Objectively assign overhead costs based on the cause and effect of a relevant cost driver to activities
   		Help businesses better analyze the cost of making and delivering items
   		Show the profitability by segment of the company
   		Allow for more accurate product overhead costing

Suppose that we have a process that produces two types of an item: Blue Item and Orange Item. Both of the items require the same pure sequential operations: O1, O2, O3. O1 and O3 are manual operations. O2 is the main and an automated operation which differentiates the items (e.g. gives different colors). Operation 1 takes 1 minutes per item. It is a manual operation that is common to both types. Operation 2 takes 4 minutes per item. It is an automated operation. Operation 3 takes 1 minute per item. It is a manual operation that is common to both types. Draw the GANTT Chart, calculate the flow time, cycle time, throughput, value added time and waste when the setup time for machine 2 where the Operation 2 occurs is 3 minutes and the batch size is 3 items per batch.

Toyota used to sit on top of the world. It basked in the reputation of building high-quality cars efficiently. It enjoyed unprecedented growth, even surpassing General Motors as the largest car manufacturer in the world. But all of that came tumbling down with reports that cars were accelerating out of control, careening down highways, and putting everyone’s lives in danger. There was even a recording of a 911 call from an off-duty policeman who lost control of his car and died in the ensuing crash. Toyota responded with a recall of historic proportions—nearly 8 million cars in the United States and 1.8 million in Europe. It even suspended sales of brand new models, including the best-selling Camry and Corolla, until the vehicles could be repaired. But still, there was confusion about what was causing the problems—was it the floor mats, the braking system, the software controlling the engine, or something else? Conspiracy theorists argued that Toyota had no clue what was causing the sudden acceleration and that their recall was basically worthless. By early 2009, your company was in a situation it had not faced for decades—its sales had dropped by 16 percent. Even General Motors, the bankrupt General Motors, which looked like it could do nothing right for many years, grew 8 percent during the same time. According to some journalists, the recall cost Toyota more than $2 billion. But by March 2010, things seemed to be on the rebound. Sales picked up dramatically, 35 percent from the previous year, and 88 percent from the previous month. Customers were once again buying Toyotas and putting their confidence in its ability to produce reliable cars. But just as things seemed to be rosy again, Transportation Secretary Ray LaHood announced plans to levy a fine of $16.4 million against your company. The money itself isn’t necessarily a problem. Even with losses, Toyota still made $1.8 billion in the fourth quarter of 2009. The fine would be less than 1 percent of what you earned in just three months. So why not just “take the medicine” as it were, pay the fine, and move on from the whole mess? Because the fine comes attached with a statement that Toyota “knowingly hid” safety problems in order to avoid a costly recall. According to LaHood, “We now have proof that Toyota failed to live up to its legal obligations. Worse yet, they knowingly hid a dangerous defect for months from U.S. officials and did not take action to protect millions of drivers and their families.” So what will you choose to do? You could just pay the fine and admit fault, but if you do, the company’s reputation for quality will take a perhaps fatal blow. You wouldn’t just be admitting that you made a mistake, but that you deliberately lied about it in order to keep making money. What’s more, an admission of covering up would give great support to the hundreds of lawsuits that claim Toyota committed consumer fraud. How much money would those settlements cost? You could, of course, just contest the fine and the admission. But, your company’s reputation is already fragile, and fighting the government (and potentially losing) may make things even worse. Form a group with three or four other students and discuss what decision you would make as a Toyota management team by answering the following questions. 1. What is your recommendation for how Toyota should approach this situation? 2. What are the decision criteria that should be used in this situation, and how should they be weighted? 3. Under what conditions do you think it is acceptable for Toyota to settle for a “good enough” decision?
