One mole of an ideal gas (CP/R=7/2), is compressed in a steady-flow compressor from 2.5 bar and 25°C to 6.5 bar and 120°C. The compressor rejects 0.5 kJ as heat to the surrounding at 293K.
Calculate:
1. The enthalpy change of the gas (in kJ)
2. The entropy change of the gas (in J.mol-1)
3. The work required for the compression (in kJ)
4. The ideal work of the process (in kJ)
5. The thermodynamic efficiency
The lost work (in kJ)

Write a response on a Professional Issue within Nursing of your choosing. Select a minimum of two (2) research articles from scholarly, peer-reviewed (refereed) journals regarding the Professional Issue and its relevance to current nursing practice. The assignment can compare and contrast the different sides to an issue, provide support to one side of an issue, or to create an action plan of how to manage a situation. Use critical thinking to analyze and evaluate the issue chosen. The articles must be current to within the past seven (7) years.
Some examples of Professional Issues within Nursing include, but are not limited to: • Access to healthcare • Nurse to Nurse Bullying • Disparities in healthcare • Health insurance coverage, health care financial concerns or fiscal responsibility • Importance of orientation to retention of nurses • Infections (CAUTI, sepsis), staffing needs, and scheduling practices and other safety concerns • Malpractice or other legal responsibilities • Withdrawing treatment vs. Advanced directives and other ethical concerns • The move toward more community care and other community concerns • Ideas on how to deal with conflict or have difficult discussions, how to use therapeutic communication in the workplace, giving specific examples.

"To Breakfast or Not to Breakfast?" by Richard Ayore
In the American society, birthdays are one of those days that
everyone looks forward to. People of different ages and peer groups
gather to mark the
18th, 20th, ,
birthdays. During this time, one looks back to see what he or
she has achieved for the past year and also focuses ahead for more
to come.
If, by any chance, I am invited to one of these parties, my
experience is always different. Instead of dancing around with my
friends while the music is booming, I get carried away by memories
of my family back home in Kenya. I remember the good times I had
with my brothers and sister while we did our daily routine.
Every morning, I remember we went to the shamba (garden) to weed
our crops. I remember one day arguing with my brother as to why he
always remained behind just to join us an hour later. In his
defense, he said that he preferred waiting for breakfast before he
came to weed. He said, "This is why I always work more hours than
you guys!"
And so, to prove him wrong or right, we decided to give it a try.
One day we went to work as usual without breakfast, and recorded
the time we could work before getting tired and stopping. On the
next day, we all ate breakfast before going to work. We recorded
how long we worked again before getting tired and stopping. Of
interest was our mean increase in work time. Though not sure, my
brother insisted that it was more than two hours. Using the data in
the table below, solve our problem. (Use
α = 0.05)
State the distribution to use for the test. (Enter your answer in the form z or tdf where df is the degrees of freedom.)
Part (e)
What is the test statistic? (If using the z distribution round your answer to two decimal places, and if using the t distribution round your answer to three decimal places.)
Part (f)
What is the p-value?
| Work hours with breakfast | Work hours without breakfast |

Assignment Overview IN C++ This assignment will give you practice with numerical calculations, simple input/output, and if-else statements. Candy Calculator [50 points] The Harris-Benedict equation estimates the number of calories your body needs to maintain your weight if you do no exercise. This is called your basal metabolic rate or BMR. The calories needed for a woman to maintain her weight is: BMR = 655 + (4.3 * weight in pounds) + (4.7 * height in inches) - (4.7 * age in years) The calories needed for a man to maintain his weight is: BMR = 66 + (6.3 * weight in pounds) + (12.9 * height in inches) - (6.8 * age in years) A typical chocolate bar will contain around 230 calories. Write a program that allows the user to input their weight in pounds, height in inches, and age in years. Ask the user to input the string “M” if the user is a man and “W” if the user is a woman. Use only the male formula to calculate calories if “M” is entered and use only the female formula to calculate calories if “W” is entered. Ask the user if he or she is: A. Sedentary B. Somewhat active (exercise occasionally) C. Active (exercise 3-4 days per week) D. Highly active (exercise every day) If the user answers “Sedentary” then increase the calculated BMR by 20 percent. If the user answers “Somewhat active” then increase the calculated BMR by 30 percent. If the user answers “Active” then increase the calculated BMR by 40 percent. Finally, if the user answers “Highly active” then increase the calculated BMR by 50 percent. The program should then output the number of chocolate bars based on the BMR value that should be consumed to maintain one’s weight for both a woman and a man. Input Errors If the user enters an age either < 1 or > 100, instantly end the program with an error message. If the user enters a height < 10 or > 100, instantly end the program with an error message. If the user enters a weight < 10 or > 500, instantly end the program with an error message. You can assume that the user does not type some non-numeric value. You don't have to test for this kind of non-numeric error. If the user does not enter ‘M' for male calculation or 'F' for female calculation, instantly end the program with an error message. If the user does not enter A, B, C, or D when prompted, instantly end the program with an error message. These limits must be defined as symbolic constants, which should be used throughout the program. Submit at least three sample runs that show possible run-time errors. Also demonstrate the capacity to get a single letter from the user, showing at least one user-input error (an illegal choice) and one bad numeric input (out-of-range error).

JK Products is evaluating an investment in either of two competing projects that will allow the company to eliminate a production bottleneck and meet the growing demand for its products. The company’s engineering department narrowed the alternatives down to two –MD and HD. A project specialist developed the following estimates of cash flows for MD and HD over the relevant six-year time horizon. The company has an 11% required return and views these projects as equally risky.
| Project MD | Project HD | |
| Initial Outflow (CF0) | R670,000 | R940,000 |
| Year (t) | Cash Inflows (CFt) | |
| 1 | R250,000 | 170,000 |
| 2 | 200,000 | 180,000 |
| 3 | 170,000 | 200 000 |
| 4 | 150 000 | 250 000 |
| 5 | 130 000 | 300 000 |
| 6 | 130 000 | 550 000 |
Required:
2.1.Calculate the net present value (NPV) of each project, assess its acceptability and indicate which project is best, using NPV.
2.2. Calculate the internal rate (IRR) of each project, assess its acceptability and indicate which project is best, using IRR.
2.3.Calculate the profitability index (PI) of each project, assess its acceptability, and indicate which project is best, using PI.
2.4.Draw the NPV profile project SQ and HT on the same set of axes and use this diagram to explain why the NPV and the IRR show differences for these two mutually exclusive projects. Discuss this difference in terms of both the “scale problem” and the “timing problem”.
2.5.Which of the two mutually exclusive projects would you recommend that JK Products undertake? Why?
