  2. CHEGR 2683 Grading Policy * The better of the cumulative quiz scores and the final exam score will be used for the final grade.

  3. Supplemental Instruction (SI)Fall 2006 Ask your instructor about participating in SI

  4. Spring 2006 Results for SI GPA 10+ = Students who attended 10 or more study sessions

  5. Previous Project

  6. Chapter 2 • Units of Measurement • Force/Weight

  7. Quote from H. Klesch, B.E ChE 2004 August Mack Environmental Lastly, for all the young kids who hate converting, it's amazing how much converting you really do in a job. Everyday I am converting from English to metric and vice versa, or the boss will ask what equivalent units there are for something and what it means or given a number, put it in a way we can understand. Most of the time though we have to report in certain units only and all the information is in units long from the one you want.

  8. Quote from D. Oaks Former YSU ChE Sophomore I will be going to OSU in the fall and they said I have the knowledge of a junior. They were impressed with the fact of CHEMCAD being introduced so early and knowing Excel. They only use Excel for printing imported things.

  9. Rest of the World kg or metric tonne m m3 or liter N J or kW-hour W Pa or kPa or bar United States lbm or ton (short/long) ft ft3 or gallon or barrel lbf Btu or hp-hour hp atm or psi or in. Hg or mm Hg or torr Common Units in Engineering

  10. Common Errors • Metric tonne or American Engineering ton • Fluid ounce or mass ounce • lbm or lbf • American Engineering gallon or Imperial gallon • Barrels: • 1 Barrel US liquid = 31.5 gallons • 1 Barrel US oil = 42 gallons

  11. Engineering Calculations must Always be Correct with Respect to Units of Measurement

  12. Force and Weight • Force = Mass x Acceleration • Newton, lbf • Weight = Mass x Acceleration of gravity • Newton, lbf • 1 Newton = 1 kg accelerating at 1 m/s2 • 1 lbf = 1 lbm accelerating at 32.174 ft/s2

  13. Weight of 10 kg on Earth

  14. Weight of 10 lbm on Earth

  15. Chapter 3 • Density/Specific Gravity • Chemical Composition • Liquid Static Pressure
