Compute the minor (local) head loss and pressure drop for pipe fittings, valves and bends: h_m = K·v²/(2g), ΔP_m = K·ρ·v²/2. Ships typical K values for 14 common components (gate/globe/check/angle/ball valves, 90°/45° elbows, tees, sudden contraction/expansion, sharp entrance/exit); choose a preset or supply a custom K. Supports n identical fittings in series. Returns head loss (m, ft) and pressure drop (Pa, kPa, bar). Density in kg/m³, g/cm³ or lb/ft³.

Compute three-phase induction motor slip: synchronous speed n_s = 60·f/p and slip s = (n_s − n)/n_s. Supports slip-from-speed and speed-from-slip modes; automatically flags generator mode (s < 0).

Build the torque-speed curve of a three-phase induction motor using the Kloss equation T/T_max = 2/(s/s_max + s_max/s). Returns rated torque, breakdown (max) torque, starting torque, breakdown slip, and a sampled T-n curve with configurable point count.
