⏳ Hourglass Sand Simulation — 2D Beverloo Flow Cross-Section

2D companion of the hourglass simulation: a cross-section of the bulbs with a growing angle-of-repose pile, the Beverloo flow rate against orifice diameter, constant sand flow compared with Torricelli water drainage, and jamming for small orifices.
