A semester projectect is required for this course. The project will consist of the development of a fluid power "calculator" and design guide using MicroSoft Excel. The project may be completed individually or as team with no more than 2 persons per team. "Modules" will be developed as sequential topics are covered throughout the semester. Modules will consist of pages or macos in Excel which contain formulas (developed for both the English and Metic system) that perform specified minimum calculations and/or component selection criteria. A separate module will be required to perform the following calculations or selections:
1. Calculate Pressure given force and area;
2. Calculate Force, given Pressure and Area;
3. Calculate Bore, given Force and Pressure;
4. Calculate Fluid Horsepower;
5. Calculate Torque Horsepower;
6. Calculate Brake Horsepower;
7. Calculate Volumetric Efficiency;
8. Calculate Mechanical Efficiency;
9. Calculate Overall Efficiency;
10. Calculate Fluid Properties:
1. Specific Gravity, Given weight density;
2. Weight Density; Given Specific Gravity;
3. Kinematic Viscosity (ISO) to SSU Conversions
4. SSU to ISO Conversions;
5. Visicosity Index
11. Size Conductors (Based on recommended fluid velocity and system pressure) for:
Piping (schedule 40)
Tubing (standard wall thicknesses)
Flexible Hose (Based on SAE standards)
12. Calculate pressure losses through:
Valves and fittings;
Lines and circuits;
Orfices
13. Calculate Pneumatic Consumption Rates for
Cylinders;
Motors;
Workstations;
Systems
14. Calculate Required Horsepower for compressors
15. Calculate Receiver size for pneumatic systems
16. Calculate pressure losses for pneumatic distribution lines.
No Elevation Specified--pressure drops are solely based on frictional losses. | |||||||
