  14. WHAT IS “AVERAGE RESIDENCE TIME”? Volume of Store = $10 bills $ $ $ $ ? $ $ $ $ $ $ Output = $1 bill per day Input = $1 bill per day On average, how many days is the “red” dollar bill likely to stay in the store?

  15. AVERAGE RESIDENCE TIME Volume of Store = $10 bills $ $ $ $ ? $ $ $ $ $ $ Output = $1 bill per day Input = $1 bill per day On average, how many days is the “red” dollar bill likely to stay in the store? 10 days.

  16. AVERAGE RESIDENCE TIME What happens if I increase the number of bills in the store to 20? Volume of Store = $20 bills $ $ $ $ $ $ $ $ ? $ $ $ $ $ $ $ $ $ $ $ $ Output = $1 bill per day Input = $1 bill per day On average, how many days is the “red” dollar bill likely to stay in the store?

  17. AVERAGE RESIDENCE TIME What happens if I increase the number of bills in the store to 20? Volume of Store = $20 bills $ $ $ $ $ $ $ $ ? $ $ $ $ $ $ $ $ $ $ $ $ Output = $1 bill per day Input = $1 bill per day On average, how many days is the “red” dollar bill likely to stay in the store? 20 days!

  18. AS SIZE OF STORE INCREASES • AVERAGE RESIDENCE TIME INCREASES.

  19. AVERAGE RESIDENCE TIME What happens if I increase the rate of inputs and outputs of bills in the store to 10? Volume of Store = $10 bills $ $ $ $ ? ? $ $ $ $ $ $ Output = 2 dollar bills per day Input = 2 dollar bills per day On average, how many days is a “red” dollar bill likely to stay in the store?

  20. AVERAGE RESIDENCE TIME What happens if I increase the rate of inputs and outputs of bills in the store to 10? Volume of Store = $10 bills $ $ $ $ ? ? $ $ $ $ $ $ Output = 2 dollar bills per day Input = 2 dollar bills per day On average, how many days is a “red” dollar bill likely to stay in the store? 5 days!

  21. AS RATES OF INPUTS AND OUTPUTS (AVERAGE FLUX) INCREASE. • AVERAGE RESIDENCE TIME DECREASES.

  22. Avg. Residence = 1,338,000,000 / 484,680 = 2760 years

  23. Avg. Residence = 47,659,600 / 132,710 = 359 years

  24. Avg. Residence = 12,900 / 577,000 = 0.02 yrs (7.3 days)

  25. 0.02 yrs 400 yrs 2-3,000 yrs

  26. Kinetic Energy -: By virtue of motion

  27. Potential Energy -: By virtue of position above some datum Increasing Potential Energy 3. 2. 1. Sea –level datum

  28. GRAVITY CONVERTS POTENTIAL TO KINETIC Potential Energy increased by Impounding water behind dam. Raises reservoir level Converted to Kinetic Energy to drive turbines.
