CLASSIFICATION OF FLUID FLOW AND THE CONTINUITY EQUATION 5.1 Classification of Fluid Flow Uniform flow If the velocity of the fluid is the same in magnitude and direction at every point in the fluid the flow is said to be uniform. Non-uniform flow A non-uniform flow is one where the velocities at different points at a given instant are not the same. Every fluid that flows near a solid boundary will be non-uniform because the fluid at the boundary takes the velocity of the boundary which is usually zero

its self on earth. All organisms need other organisms for survival. An ecosystem is a community of living organisms. An ecosystem maintains an important balance in order for all organisms within the ecosystem to survive. The balance involves carbon‚ food‚ nitrogen‚ oxygen and water. The sun supplies the energy needed by ecosystems. Plants absorb the energy and use photosynthesis to convert it to sugar. There are nutrients in the air‚ soil and water that keep the ecosystem growing and balanced.

Overview IAS 7 Statement of Cash Flows requires an entity to present a statement of cash flows as an integral part of its primary financial statements. Cash flows are classified and presented into operating activities (either using the ’direct’ or ’indirect’ method)‚ investing activities or financing activities‚ with the latter two categories generally presented on a gross basis. IAS 7 was reissued in December 1992‚ retitled in September 2007‚ and is operative for financial statements covering periods

Profitability Ratios: How Profitable is the Company? Net sales/Net profit after taxes The information necessary to determine a company’s profit as a percentage of sales can be found in the company’s income statement. 1. Magnetronics’ profit as a percentage of sales for 1999 was $1‚307 divided by $48‚769‚ or 2.68%. 2. This represented a decrease from 3.6% in 1995. 3. The deterioration in profitability resulted from a decrease in cost of goods sold as a percentage of sales‚

USE-CASE DIAGRAM EXERCISE 1. Draw a use case diagram for an ATM machine with the following functionality. A customer’s interaction with the system involves logging in‚ making withdrawal requests‚ deposit requests‚ and balance inquiry requests. If the customer logs in‚ there is a possibility (although rare) that the system will confiscate the card (for example‚ if the login is incorrect or if the bank determines that the customer’s balance is significantly under zero). Card confiscation involves

CIRCULAR FLOW OF INCOME The Circular Flow of Income‚ expenditure and output is a model of the economy which shows the movement of goods and services between households and firms and their corresponding payments in money terms Money circulates from households to firms and back again. The more a households spend and the more firms produce‚ the higher the levels of income. Income + output in economy should always be same and are measured by GDP. Circular Flow emphasizes importance of interactions

Free-body diagrams are diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation. A free-body diagram is a special example of the vector diagrams that were discussed in an earlier unit. These diagrams will be used throughout our study of physics. The size of the arrow in a free-body diagram reflects the magnitude of the force. The direction of the arrow shows the direction that the force is acting. Each force arrow in the diagram is labeled

Nutrients Pigments and photosynthesis 1. Distinguish between the strategies used by autotrophs and heterotrophs to obtain free energy for cellular processes. In other words‚ how and in what form does each capture and store that energy? 2. Explain how photosynthesis differs in eukaryotic organisms (with organelles such as chloroplasts) and in prokaryotic organisms (single-celled‚ no organelles). 3. How does a metabolic pathway such as photosynthesis suggest common ancestry? 4. Describe
