Efficient Propeller Design | AbstractHow does a helicopter generate enough lift to fly? How does a speedboat get moving fast enough to pull someone on water skis? Here ’s a project on designing propellers to do the job. ObjectiveThe goal of this project is to investigate how changes in chord length affect the efficiency of propellers.IntroductionA propeller‚ like an airplane wing‚ is an airfoil: a curved surface that can generate lift when air moves over it. When air moves over the surface of

1.) ‘The free market is the most efficient way of allocating resources in Singapore.’ Do you agree? Every society in the world‚ including Singapore faces the basic problem of scarcity. I.e Allocating resources occurs because there is unlimited human wants and limited resources‚ hence the problem of scarcity derives. There is three basic choices to be made: What‚ How‚ and for Whom to produce. Where the choice of what to produce is dependent on product prices‚ Product prices are determined

The poem‚ “When I Have Fears that I May Cease to Be”‚ by John Keats‚ uses metaphor‚ romantic imagery‚ and figurative language to reflect the speaker’s fear of dying without accomplishing what he aspires for in life which is success and fame in his writing and the love of one who will never love him back.

such as red cod‚ spotty and kahawai challenge them. There are predators such as dolphins‚ sharks and also people. Their gas exchange system has to be efficient for them to be able to compete with those fish and escape from predators. Fish live in an acquatic environment. Water contains a less % 02 than the air so fish mush have a very efficient gas exchange system. This has prompted the development of the gill system. Air has 20% 02‚ water has much less. The gills are supported by the gill arch

‘Differences in men’s and women’s speech may be partly based on social factors’ Many works have been devoted to the differences in communication between people.

Instructions for Efficient-Frontier Construction a. Estimation The goal is to obtain the raw ingredients – expected returns‚ standard deviations and correlations. Historical data are used for this purpose. As a rule of thumb‚ five years of daily data are probably right (one year should be the absolute minimum). Keep in mind the following: 1) make sure to use the adjusted close prices to calculate returns (so that you won’t have large‚ spurious negative returns due to dividend payments or splits)
