Since the slope of the 2D tank can be freely changed, it is possible to control the slope of the water surface. A rectifying tank is provided at the top, and an upper and lower gate is provided at the downstream. Overflow and drilling experiments can be performed without replacing the gate. In addition, this gate can be sealed and used as a water tank. There are wide glass windows on both sides of the aquarium.
Continuous experiments of circulation devices (composition: high water tank, test tank, low water tank, water supply device) become possible. (We will design and manufacture other measuring devices according to the purpose of the test.)
