Variable Geometry Turbocharger Turbochargers works on the simple principle of increasing the intake air density by compression. Being able to fill more air into the combustion chamber will allow more fuel to be added to produce more power. However the operation of the turbocharger relies solely on the exhaust gas velocity to drive the compressor. Thus the compressor will be at optimum operation range when the engine is under heavy load. When the throttle is opened‚ it will take a certain period

able to determine whether a cost is fixed or variable is vital to the understanding of overhead loading and cost behavior. A fixed cost is unchanged with a change to the cost driver. (Horngren‚ Sutton‚ and Stratton p.46) Which means that a fixed cost does not rise with the change is production of your product. A good example of a fixed cost is rent. No matter how many widgets you make (within a relevant range) your rent will not increase. A variable cost‚ on the other hand‚ does change with the

Two-Variable Inequalities Kathleen Kent MAT 222 Week 2 Assignment Guillermo Alvarez September 22‚ 2014 Two-Variable Inequalities This week’s assignment will show how two-variable inequalities can be used in real-world scenarios by using independent and dependent variables. This week’s assignment will use graph representations and show how the two-variable inequalities can be incorporated into several problems to show how many of each item trucks can ship without going over

WHAT IS A RANDOM VARIABLE? A random variable assigns a number to each outcome of a random circumstance‚ or‚ equivalently‚ a random variable assigns a number to each unit in a population. It is easier to create rules for broad classes of situations and then identify how a specific example fits into a class than it is to create rules for each specific example. We can employ this strategy quite effectively for working with a wide variety of situations Involving probability and random outcomes. We
