WHAT IS “AVERAGE RESIDENCE TIME”? $ $ $ $ $ $ $ $ $ $? Volume of Store = $10 bills Input = $1 bill per day Output = $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 Input = $1 bill per day Output = $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 $ $ $ $ $ $ $ $ $ $? Volume of Store = $20 bills Input = $1 bill per day Output = $1 bill per day On average, how many days is the “red” dollar bill likely to stay in the store? $ $ $ $ $ $ $$ $ $ What happens if I increase the number of bills in the store to 20?
17
AVERAGE RESIDENCE TIME $ $ $ $ $ $ $ $ $ $? Volume of Store = $20 bills Input = $1 bill per day Output = $1 bill per day On average, how many days is the “red” dollar bill likely to stay in the store? 20 days! $ $ $ $ $ $ $$ $ $ What happens if I increase the number of bills in the store to 20?
18
AS SIZE OF STORE INCREASES AVERAGE RESIDENCE TIME INCREASES.
19
AVERAGE RESIDENCE TIME $ $ $ $ $ $ $ $ $ ? Volume of Store = $10 bills Input = 2 dollar bills per day Output = 2 dollar bills per day On average, how many days is a “red” dollar bill likely to stay in the store? What happens if I increase the rate of inputs and outputs of bills in the store to 10?
20
AVERAGE RESIDENCE TIME $ $ $ $ $ $ $ $ $ ? Volume of Store = $10 bills Input = 2 dollar bills per day Output = 2 dollar bills per day On average, how many days is a “red” dollar bill likely to stay in the store? 5 days! What happens if I increase the rate of inputs and outputs of bills in the store to 10?
21
AS RATES OF INPUTS AND OUTPUTS (AVERAGE FLUX) INCREASE. AVERAGE RESIDENCE TIME DECREASES.
23
Avg. Residence = 1,338,000,000 / 484,680 = 2760 years
24
Avg. Residence = 47,659,600 / 132,710 = 359 years
25
Avg. Residence = 12,900 / 577,000 = 0.02 yrs (7.3 days)
26
2-3,000 yrs 0.02 yrs 400 yrs
27
Kinetic Energy -: By virtue of motion
28
Potential Energy -: By virtue of position above some datum Sea –level datum 1. 2. 3. Increasing Potential Energy
29
GRAVITY CONVERTS POTENTIAL TO KINETIC Potential Energy increased by Impounding water behind dam. Raises reservoir level Converted to Kinetic Energy to drive turbines.
