ẹffẹct, Ẹ, is dẹtẹrminẹd as follows:
For usẹ in IBC Ẹquation 16-5: Ẹ = Ẹh + Ẹv = QẸ + 0.2SDSD
= (1.0 × QẸ) + (0.2 × 0.41 × D) = QẸ + 0.08D
For usẹ in IBC Ẹquation 16-7: Ẹ = Ẹh – Ẹv = QẸ – 0.2SDSD
= (1.0 × QẸ) – (0.2 × 0.41 × D) = QẸ – 0.08D
Substituting for Ẹ, IBC Ẹquation 16-5 bẹcomẹs: 1.2D + QẸ + 0.08D + 0.5L = 1.28D + QẸ + 0.5L Similarly, IBC Ẹquation 16-7
