or I could enter N=0.013, Q= no input, D=15 (inches), S=.01, Y= no input and it would calculate the flow "Q" in CFS that a 15 inch concrete pipe can carry at 1%.

Does it mean that "Y= no input" implies y=d?
In this case the formulas are much simpler:

• \(A=\frac{\pi}{4}d^2\)
• \(P=\pi d\)
• \(R=\frac{d}{4}\).
  

Could it be that you specified: N, Q, D, S and then y was calculated?
