电机驱动强迫涡实验仪（转速显示）
A forced vortex is solid body rotation, and the surface rise depends only on speed and radius, which students can check exactly. The 300 mm clear vessel spins on a turntable at 0–200 rpm with a 1 rpm digital readout. A traversing 0–300 mm depth gauge with 0.1 mm resolution maps the paraboloid across a 0–150 mm radial scale.
