  1. One important point for an automobile radiator design is to cool the engine while moving at 50 km/h on a 7% grade road in a desert summer condition. Your responsibility as a design engineer is to make sure that the coolant (water in this case, since it is the hot summer time, no antifreeze is needed) temperature at the radiator inlet does not exceed the saturation temperature of water at this point. Consider a radiator that can be approached as a cross – flow heat exchanger with both fluids unmixed and working under the following conditions:

The manometer reading at the radiator water inlet is 100 kPa (the gage pressure!) where the local atmospheric pressure is also 100 kPa.

The engine heat rejection rate: q = 40 kW.

For air; flow rate 2700 kg/h, inlet temperature 52 , specific heat 1008 J/kg.K.

For water; flow rate 5130 kg/h, specific heat 4244 J/kg.K.

For the radiator UA = 1134 W/K.

  1. Determine the water inlet and outlet temperatures and air outlet temperature from the radiator. (15 P)
  2. Determine the logarithmic mean temperature difference correction factor F and estimate the value of corrected logarithmic mean temperature difference for the radiator. (10 P)
  3. Neglecting the pressure losses within the radiator, determine whether the design is safe or not against overheating (against boiling within the radiator). (15 P)
  4. One effective way of obtaining safe operating conditions against radiator overheating may be increasing fan power to obtain higher air flow rates. If your findings for Part c) indicate unsafe operating conditions, determine the minimum air flow rate that ensures safe operation against the radiator overheating. To do this, increase the air flow rate with 90 kg/h intervals, until yuo reach safe operating conditions, while keeping the other parameters fixed at the above given values. (15 P)
  1. A low quality coal known as Saray lignite has the components of C = 45%, H = 4%, O = 17%, S = 4%, N = 2%, A = 13% and W = 15%. Carry out the following analyses for this lignite:
  1. Using the exact formula determine the heating value. (5 P)
  2. Draw the Ostwald dagram in a scaled manner. (10 P)
  3. After the combustion, 6% CO2 and 10% CO contents are measured in the stack gases. Obtain the excess air coefficient and the ratio of O2 within the stack gases, utilizing the Ostwald diagram you drew in Part b). (10 P)
  4. Determine the excess air coefficient and the ratio of O2 within the stack gases, using the analytical relations and compare the results with the ones you obtained in Part c). (10 P)
  5. In what type of boiler and under which conditions do you think this lignite should be used in the lights of above estimated values of fuel components, the excess air coefficient, and the heating value. (10 P)

Four moles of a monatomic ideal gas are taken through a three-process thermodynamic cycle. The gas initially has a pressure of 8.00 atm with a temperature of 600 K (point A). The gas it then expanded isothermally to point B where the volume is 48.0 L. The gas is compressed via an isobarically process (point C). The gas is then expanded adiabatically back to its initial state. For all calculations using the ideal gas law assume that R = 0.08 (L atm) / (mol K). For any calculations of work, heat, internal energy, or entropy use R = 8.0 J / (mol K).

a. Compute all unknown pressures, temperatures, and volumes and organize them into a table.

b. Find the work done going from point C to point A?

c. What is the heat added to the system going from A to B?

d. What is the change in internal energy going from B to C?

e. What is the change in entropy going from A to B?

pictou pallets manufatures shipping pallets at two plants and distributes them to three strategically located warehouses.

Plant 1 is capable of producing 8000 pallets per year and plant 2 is capable of producing 5000 pallets per year.

Warehouse A requires 4500 pallets, warehouse b requires 3000 pallets, and warehouse c requires 4000 pallets per year.

the cost of shipping one pallet from each plant to each warehouse are listed below:

(eg. the cost of shipping from plant 1 to warehouse A is $1.10 per pallet)

plant warehouse a warehouse b warehouse c
1 $1.10 $1.40 $1.25
2 $1.20 $0.95 $1.00

a) find the optimal shipping schedule to minimize shipping costs.

B) would the shipping schedule change if the cost of shipping from plant 1 to warehouse A increased by $0.30 to $1.40? explain

C) how much would the shipping charges change if plant 2's capacity were decreased by 100 pallets?

d) would the same hold for another decrease of 100 pallets?

E) the optimal shipping schedule has no pallets shipped from plant 1 to warehouse b. What change in shipping cost along this route would make such shipments worthwhile.

You are a middle school principal in a working-class conservative community in the Midwest. One of your tenured teachers placed a series of very negative comments about you and the school on her Facebook page. These comments were made over the weekend. A number of your students informed you that they read the teacher’s comments. In fact, you heard a group of students chatting and laughing about the comments. Additionally, you receive phone calls from a number of parents who conveyed how negative and unprofessional the teacher’s comments were.

Discussion Questions

How would you react to parents and students?

How do you approach the teacher who is allegedly responsible for the negative comments?

If evidence reveals that the teacher is responsible for these comments, what action would you take?

What options are available to you in addressing this situation?

What precautions must be taken to ensure that the teacher’s rights are protected?

How do you balance the rights of the teacher against the need to protect the integrity of the school?

Please discuss the probable consequences of each option you identified.

What is your final decision? Provide a rationale for your decision.

The Outdoor Furniture Corporation manufactures two products: benches and picnic tables, for use in yards and parks. The firm has two main resources: its carpenters (labor force) and a supply of redwood for use in the furniture. During the next production cycle, 1,200 hours of labor are available under a union agreement. The firm also has a stock of 3,500 board feet of quality redwood. Each bench that Outdoor Furniture produces requires 4 labor-hours and 10 board feet of redwood; each picnic table takes 6 labor-hours and 35 board feet of redwood. Completed benches will yield a profit of $9 each, and tables will result in a profit of $20 each. How many benches and tables should Outdoor Furniture produce in order to obtain the largest possible profit?

The optimum solution is:

Number of benches produced equals = (round your response to the nearest whole number).

Number of tables produced equals = (round your response to the nearest whole number).

Optimal solution value = $ (round your response to the nearest whole number).
