The image above represents flow at some time after recession. To calculate flow at some time after recession, three essential parameters are needed and these parameters are Flow at the Start of Recession (Qo), Recession Constant (a) and Time Since the Start of Recession (t).
The formula for calculating flow at some time after recession:
Q = Qoe-at
Where:
Q = Flow at Some Time after Recession
Qo = Flow at the Start of Recession
a = Recession Constant
t = Time Since the Start of Recession
Let’s solve an example;
Find the flow at some time after recession when the flow at the start of recession is 12, recession constant is 24 and time since the start of recession is 9.
This implies that;
Qo = Flow at the Start of Recession = 12
a = Recession Constant = 24
t = Time Since the Start of Recession = 9
Q = Qoe-at
That is, Q = (12)e-(24)(9)
Q = (12)e-(216)
Q = (12)e-216
This means that Q = (12)(1.557e-94)
Q = 1.86e-93
Therefore, the flow at some time after recession is 1.86e-93.
