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,
$$Q=(0.11)(1.25\:in/hr)(30\:acres)$$$$$Q=4.125\:ft^3/sec$$$
$$4.125\:ft^3/sec$$\$
