Mass flow To measure the gas flow rate, a glass bowl filled with water was placed on a precision balance. A vertical glass cylinder was placed above the bowl, with the lower inlet 1 cm under the water surface. At the start of the measurement, water from the bowl was drawn into the cylinder and the top of the cylinder was closed. Gas from the SBRs was led into the cylinder via a sintered glass nozzle placed under the cylinder in the bowl, and the gas flow rate was calculated from the amount of water that was displaced by the gas flow in a fixed amount of time. the liquid flow rate was also measured using a precision balance. 这是测气体流量，但不知道具体原理？先先大家乐 |
