Is Q=CiA Dimensionally Consistent?

Shed runoff flow rate Q has been computed under the Rational Method using the equation: Q = CiA for a very long time, but ever so often, a new user would ask if this equation is dimensionally consistent. In this equation, the units of Q is cfs (cubic feet per second, or ft3/sec). C is […]
