How this was calculated
TDH = Static Head + Friction Head + Pressure Head
Pressure Head (ft) = (Pd - Ps) × 2.31 / SG
Water Horsepower = Q(gpm) × TDH(ft) × SG / 3960
Brake Horsepower = WHP / pump efficiency (assumed 70%)

Total Dynamic Head (TDH) is the total equivalent height that a pump must move fluid against, considering static elevation change, friction losses, and pressure requirements at the discharge point.
In petroleum operations, TDH calculations are critical for ESP sizing in artificial lift, water injection pump selection, produced water transfer systems, and chemical injection systems.
