A thermocouple (TC) reads a temperature of 180 degrees C when placed in a large wind tunnel. The thermocouple is exposed to convection and radiation heat transfer.

• The convection heat transfer coefficient h = 125 W/m²-K.
• As for radiation, the surface of the thermocouple is diffuse and gray with an emissivity of 0.6. The walls of the wind tunnel are at a uniform temperature of 450 degrees C.

Questions:

1. Provide a sketch
2. State your assumptions
3. Calculate the temperature of the air in the wind tunnel
4. The walls of the duct have an emissivity of 0.85. Explain in one or two sentences why the emissivity of the walls should (or should not) have an effect on your answer?

Using matlab

1. Set ASIZE to 5. Write a program that creates an array of ASIZE numeric elements. Prompt the User for ASIZE numbers and store them in the array. After storing the values, calculate the sum of all the values in the array and display the sum.
2. Modify the program you wrote for Problem 5 such that it calculates the product of all the values instead of the sum.
3. Modify the program you wrote in Problem 6 such that it changes the value of each element of the array by multiplying each element of the array by 2, and then displays each element of the array.

PHP

You will be using the object oriented features of PHP to design a music album processing page.

First you will build a form page called addAlbum.php. This form will contain text fields for album title, artist, publisher (Sony, BMI, etc.) and genre. Add two more fields of your choice. You will post this form to the file process.php.

If all the fields have values, we will create a new Album object and print the details of the object. You will need to create an Album class that has private instance variables for all the fields just described. Your constructor should simply echo to the screen "Album created." If the user missed some of the form, give them a link to go back and fix.

Generate standard getters/setters

You will need to create __get and __set functions (magic functions) to allow us to set the properties of the instance variables from outside the class. You will also create a function (or method) called __toString() in the class. Calling this will return a formatted string of all the details for the album. Store the class in album.class.php.

Include a hyperlink back to add another album.

Sample output could look like this:

Album Created
Album Title: Blaze of Glory
Artist: Jon Bon Jovi
Publisher: ASCAP
Genre: Rock
Custom Field: stuff
Another Custom Field: stuff

Add another album! (This is an hyperlink to add another album)

Requirements

i. Comments on all pages, proper page names (as requested), aligned code, overall effort
ii. addAlbum.php page is complete - doctype, complete html structure and some instructions that give the user some indication of what they are to do
iii. album.class.php - contains code to define album class - as well as documentation/comments to outline how to use - see requirements for details (private vars, constructor, magic methods(__get(),__set() and __toString functions)
iv. Some type of validation used so that user knows about errors
v. Styles for all pages: Use an external stylesheet for all styles. All page content should be in a div with an id set to 'container', 650px wide and the content centered.

vi.The container div should also be centered on the screen (horizontally). The constructor text should be echoed using an <h3> tag. Please bold all labels as displayed above.
vii. Use the Button class to print the submit button on the form page addAlbum.php.

Nina Stiller is passionate about modern sculpture and works for an art dealer in New York City. In her job, she is responsible for traveling the country to assess sculptures that are being sold by private owners and determining if the art dealer should buy them. She also privately collects sculptures that she thinks are great works of art and will become valuable over time. She will sometimes sell the sculptures she owns privately if she gets an offer that will make her a lot of money. She is saving the money from the sales because she hopes to open up her own art dealership one day. Unfortunately, her boss at the art dealership discovers that she sometimes sells pieces from her private sculpture collection for a profit. Her boss wants to fire her because her private sculpture sales are a conflict of interest with her work at the art dealer.

Nina’s boss is worried that firing Nina would violate the New York law that prohibits employers from discriminating against employees for their participation in legal recreational activities pursued outside of work hours.

Use the language from the New York law that was analyzed in theNew York v. Walmartcase to explain why Nina would not be protected by this law from being fired.
