term called Q2, but we want to preserve any changes in
direction. Create a separate equation for each loop where the
head losses are added up, but instead of squaring Q, use |Q|Q
instead (with |Q| the absolute value of Q) for the
formulation so that any sign changes will reflect appropriately
in the resulting head-loss calculation.
