Liquid Viscosity Coefficient Measured by Rising-Ball Method at Different Temperatures |

Abstract: | We had been used rising-ball method instead of the traditional falling-ball method, which can control the ball rising at a constant speed to increase the measuring accuracy.Moreover,Laser photoelectric tim-er was used to record time to make the measurement more accurate.In addition,this device had water circula-tion system,which can be used to measure liquid viscosity coefficient at room temperature and variable temper-ature. |
