一种流体压强与流速关系演示仪
本技术涉及物理教学实验仪器领域，涉及一种流体压强与流速关系演示仪。
技术介绍
对于学生来说，流体压强是抽象概念，而流体压强与流速的关系更是难以理解，目前，常见的流体压强与流速关系演示仪中，带有储水槽和排水装置，在课堂上演示时不方便，不仅要备充足的水量还要将水排出，还有进气管和排气管等装置，仪器结构复杂，不利于学生理解，也有的物理教学用具将流体压强与流速的关系演示分为气体压强与流速关系和液体压强与流速关系两套演示仪，综合性差，教学效果不佳。
技术实现思路
本技术要解决的问题是提供一种流体压强与流速关系演示仪，结构简单，将抽象问题具体化可视化，实验现象明显且稳定，易于学生对流体压强与流速关系的理解和掌握。本技术采用如下技术方案实现专利技术目的：一种流体压强与流速关系演示仪，包括水槽，所述水槽一底端设置有微型水泵，所述微型水泵连接软管，所述软管上设置止水夹，所述软管连接横向粗管，所述横向粗管连接细弯管，所述细弯管口设置有活塞，所述设置有活塞的细弯管口朝向水槽，所述横向粗管和细弯管上部均连接直径相同且小于细弯管的直径的带有刻度的细长直管，所述横向粗管连接进水管，所述带刻度的细长直管顶端分别连接横向粗管和横向细管，所述横向粗管连通横向细管，所述横向粗管连接微型抽气泵。作为对本技术方案的进一步限定：所述微型水泵为15瓦稳流微型水泵。作为对本技术方案的进一步限定：所述抽气泵为110瓦稳流微型抽气泵。作为对本技术方案的进一步限定：所述横向粗管连接进水管。作为对本技术方案的进一步限定：所述细长直管刻有刻度。与现有仪器和技术相比，本技术的优点和积极效...
