A 10.00-mi2 watershed with a 100-min time of concentration receives rainfall at a rate of 2.75 in./hr for a period of 200 min. The time–area curve is shown below.

(a) Determine the peak discharge (in cfs) from the watershed if C = 0.4.

(b) Estimate the discharge rate (in cfs) 150 min after the beginning of rainfall.
