🌬️ Polder Windpump (2D): Rotor Torque, Cut-in Wind and Water Power

2D side view of a drainage windpump: a multi-blade rotor drives a constant-torque piston pump that lifts water to the river. Wind torque against pump torque sets the cut-in wind speed and the steady speed; checks cover Betz, the steady-state root, power balance, cut-in and relaxation time.
