Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation. Use variables to represent two quantities in a real-world problem that change in relationship to one another write an equation to express one quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent variable. Use ratio reasoning to convert measurement units manipulate and transform units appropriately when multiplying or dividing quantities.įluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation. Calculate flow rate, flow velocity and mechanical advantage in a hydraulic system.įluently divide multi-digit numbers using the standard algorithm.Calculate values in a fluid power system utilizing Pascal's law.Differentiate between the characteristics of pneumatic and hydraulic systems.Identify and explain basic components and functions of fluid power devices.Identify devices that utilize fluid power.

Fluid power can improve our quality of life when engineers and researchers investigate how to use this technology to become more efficient, compact and cost effective.Īfter this lesson, students should be able to:

#Power pdf basics portable

This prepares them to conduct the associated hands-on activity, using the Portable Fluid Power Demonstrator (teacher-prepared kits) to learn more about the properties of gases and liquids in addition to how forces are transmitted and multiplied within these systems.Įngineers use fluid power to impact such areas as lowering fuel consumption in the transportation industries to improving patient care in the medical industries. After a few simple teacher demos, they learn about the four components in all fluid power systems, watch two 26-minute online videos about fluid power, complete a crossword puzzle of fluid power terms, and conduct a task card exercise. Students learn background information about fluid power-both pneumatic and hydraulic systems-including everyday applications in our world (bulldozers, front-end loaders, excavators, chair height lever adjustors, door closer dampers, dental drills, vehicle brakes) and related natural laws.

Both systems contain four basic components: reservoir/receiver, pump/compressor, valve, cylinder. Please act responsibly, the author of this information and owners of this site will accept no responsibility or liability for any damage or injury caused to persons or to any third parties, property or equipment arising from the use or misuse of the information provided on the learnabout-electronics web sites.Students learn about the fundamental concepts important to fluid power, which includes both pneumatic (gas) and hydraulic (liquid) systems. You must also have the skills and equipment to work safely, and be fully aware of locally relevant health and safety issues. The information provided on this site will not alone, qualify you to work safely on power supplies. However you must realise that the voltages and currents present in many power supplies are, at best dangerous, and can be present even when the power supply is switched off! At worst, the high voltages present in power supplies can, and from time to time do KILL.

If you are considering building or repairing a power supply, especially one that is powered from mains (line) voltages the power supply modules on this site will help you understand how many commonly encountered circuits work.
