Question
Let f(1) be the rate of flow, in cubic meters per hour, of a flooding river at time t in hours.
Give an integral for the total flow of the river.
(a) Over the time period 0 <t< 120.
120
Total flow =
f(t) dt cubic meters.
120
f(t)
dt cubic meters.
Total flow =
t
120
Total flow =
I f'(1) dt cubic meters.
120
Total flow =
| tf' (1) dt cubic meters.
120
Total flow
tf(t) dt cubic meters.
(b) In terms of T in days, for the same time interval.
Total flow =
f(24T) dT cubic meters.
Total flow
f(T) dT cubic meters.
5
Total flow
f(24T)24 dT cubic meters.
Total flow
| f'(24T)24 dT cubic meters.
Total flow
| f(24T)24T dT cubic meters.
