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. 這是測氣體流量,但不知道具體原理?先先大家樂 |

質(zhì)量流量 為測定氣體流速率,將一個(gè)裝滿水的玻璃杯放置在精密天平上。將一個(gè)玻璃量筒垂直置于杯中,入口低于水面1厘米。在開始測量的時(shí)候,量筒中充滿了杯中的水,同時(shí)量筒頂部是關(guān)閉的。來自SBRs的氣體通過位于在杯中量筒下的燒結(jié)玻璃噴嘴進(jìn)入量筒,氣體流速率是根據(jù)一段固定時(shí)間內(nèi)代替氣流的水的質(zhì)量來計(jì)算的。液體流速率也可利用精密天平來測定。 |

質(zhì)量測量法 為了測量氣體的流速,我們?nèi)∫粋(gè)玻璃質(zhì)的碗裝水后放置在精確天平上。一個(gè)玻璃圓柱垂直于此碗放置,圓柱底深入水中1厘米。在測量的初始階段,碗里的水被吸入圓柱體內(nèi),然后封閉圓柱的頂部。SBRs中的氣體通過一個(gè)放置于圓柱下、玻璃碗中的玻璃噴嘴倒入這個(gè)玻璃圓柱內(nèi),氣體的流量通過測量一定時(shí)間內(nèi)氣體排出水的量計(jì)算得到。水的量是通過精確天平稱量得到的。 |
