变水头孔口与管嘴出流实验仪
Reservoir and tank drawdown problems are best understood by timing a real tank as it empties. The 300 mm clear cylinder holds up to 550 mm of water and accepts four 10 mm fittings: sharp orifice, bellmouth, cylindrical and convergent mouthpieces. Students run constant or falling head tests, timing level drops with a 0.01 s digital timer.
