ASSIGNMENT 1

TOPIC: INTRODUCTION OF FLUID MECHANICS

QUESTION 1: 10 MARKS

In your own words, explain what have you learnt from fluid mechanics course.

QUESTION 2: 40 MARKS

Refined crude oil has been used to lubricate moving parts in a wide variety of machines and engines. These petroleum-based lubricants are extracted from natural crude oil, and must be refined, desalted, dewaxed, and distilled from crude feedstock. However, recently, engineers are moving towards non-petroleum based lubricants or known as synthetic lubricants. Obtain information about non-petroleum based lubricants and summarize your findings in a brief report by following the format given below. The report should contain minimum 1500 words (excluding figure and table title and content, references)

QUESTION 3: 50 MARKS

It is predicted that nanotechnology and the use of nano sized objects will improvise many processes and products. Among new new nanotechnology areas is that of nano scale fluid mechanics or known as nanofluid. Fluid behavior at the nano scale can be entirely different than that for the usual everyday flows. Obtain various information of nano fluid mechanics and summarize your findings in a brief report by following the format given below. The report should contain minimum 1700 words (excluding figure and table title and content, references)

4 charges are fixed to the corners of a square of side .53 cm. Charge 1 of -1 uC is fixed to the top left corner. Charge 2 of -2uC is fixed to the top right corner, charge 3 of 3uC is fixed to the bottom left corner , and charge 4 of -4uC is fixed to the bottom right corner. a) find the magnitude and direction of the electric field at the center of the square b) find the potential at the center c) find the electric potential energy of the system.

What is one significant way the Renaissance represents "rediscovery" of classical antiquity? Please identify your example as well as the author/artist/architect responsible for it, and explain exactly how it was inspired by antiquity. For example, was your author imitating a certain literary style from the ancient world, or discussing a subject germane to it?

if you were the state epidemiologist and it was suspected that smoke from the local toy factory was connected to adverse health outcomes among the town’s residents, what type of cohort study would you conduct to further investigate this concern? Why? What limitations exist in your choice of study? Remember to cite sources where necessary.

In python 3 please:

This program extends the earlier "Online shopping cart" program. (Start working from your Program 7).

(1) Build the ShoppingCart class with the following data attributes and related methods. Note: Some can be method stubs (empty methods) initially, to be completed in later steps.(3 pt)

● Parameterized constructor which takes the customer name and date as parameters

● Attributes

• ○ customer_name (string)

• ○ current_date (string)

• ○ cart_items (list)

● Methods

○ add_item()

■ Adds an item to the cart_items list. Has parameter ItemToPurchase. Does not return anything.

○ get_cost_of_cart()

■ Determines and returns the total cost of items in the cart. Has no parameters.

○ print_total()

• Outputs total of objects in the cart.

• If the cart is empty, output this message:

SHOPPING CART IS EMPTY

○ print_descriptions()

■ Outputs each item's description.

Ex. of print_total() output:

John Doe's Shopping Cart - February 1, 2016
Number of Items: 8

Nike Romaleos 2 @ $189 = $378
Chocolate Chips 5 @ $3 = $15
Powerbeats 2 Headphones 1 @ $128 = $128

Total: $521

Ex. of print_descriptions() output:

John Doe's Shopping Cart - February 1, 2016

Item Descriptions
Nike Romaleos: Volt color, Weightlifting shoes Chocolate Chips: Semi-sweet
Powerbeats 2 Headphones: Bluetooth headphones
