Flow Rate

What is the flow rate (cfs) of a 30-acre parcel of land that has a rainfall intensity of 1.25 in./hr, and a rational method runoff coefficient $$C$$ of 0.11?

Hint
$$$Q=CIA$$$
where $$Q$$ is the peak discharge, $$C$$ is the runoff coefficient, $$I$$ is the rainfall intensity, and $$A$$ is the watershed area in acres.
Hint 2
Solve for peak discharge.
Rational Formula:
$$$Q=CIA$$$
where $$Q$$ is the peak discharge, $$C$$ is the runoff coefficient, $$I$$ is the rainfall intensity, and $$A$$ is the watershed area in acres. Thus,
$$$Q=(0.11)(1.25\:in/hr)(30\:acres)$$$
$$$Q=4.125\:ft^3/sec$$$
$$$4.125\:ft^3/sec$$$
