- Abstract:
- We use the U-type height method to measure the liquid density. The system is like a U-type manometer, while the different liquid used in the tubes. One of the tube was set to the air pressure, another one was decreased the pressure below 1 atm. When a lower pressure was pumped into the tube from the top end, the heights of the level of liquid were measured. Then we got the density of the liquid.
During the experiment, the laser interferometer and proper floating reflectors were used. We utilized these instruments to measure the levels of the liquid. These results for measuring water and alcohol will be presented in the conference. - Keywords:
