Bình Chứa Nước Cho Thí Nghiệm Fluid Dynamics

I wanted a small water reservoir for my students to use when investigating fluid dynamics. This one has lines on the front face every 5 mm. If you shine enough light through the top, you should be to see the water level on the lines. 

If you have the force meter scale conversion, you can put this water reservoir on top of it and measure the weight change. The water will block a photogate, so you can get measurements for the velocity based on the distance and timing.

Enjoy!
