标题： A Fluids Experiment for Remote Learners to Test the Unsteady Bernoulli Equation Using a Burette

摘要： 新冠疫情凸显了同时可在多种模式（面对面、混合和远程）部署的灵活机械工程实验室的紧迫需求。 一位具有前瞻性的工程教师课程组合中的关键要素是经济、实用、易用的“即插即用”实验活动；这些套件既可在实体教学实验室中使用，也可邮寄给远程学习者。 能源工程实验模块的教学方法在其他地方有所描述，它提供了实现这些特性的理论基础和示例。 此外，教学实验套件必须展示基础工程现象，同时在合理成本下保持测量精度和真实性。 在能源-热流体科学领域，实现这些条件具有挑战性，因为套件需要实时传输和转换能量和物质，在足够大的尺度上揭示可测量的现象，但又不至于对用户造成危险。 本文介绍了适合本科生工程学生的流体力学实验的理论基础和实验验证，该实验满足以下所有条件：1）符合上述所有描述的标准，2）材料成本低于30美元，3）可以轻松邮寄给远程学习者。 显示英文摘要

摘要： The COVID-19 pandemic illuminated the critical need for flexible mechanical engineering laboratories simultaneously deployable in multiple modalities: face-to-face, hybrid, and remote. A key element in the lesson portfolio of a forward-looking engineering instructor is economical, hands-on, accessible, 'turn-key' lab activities; kits that can be deployed both in brick-and-mortar teaching labs and mailed home to remote learners. The Energy Engineering Laboratory Module pedagogy, described elsewhere, provides an underpinning theoretical framework and examples to achieve these features. In addition, instructional lab kits must demonstrate foundational engineering phenomena while maintaining measurement accuracy and fidelity at reasonable cost. In the energy-thermal-fluid sciences, achieving these conditions presents challenges as kits require energy and matter transport and conversion in real time at scales large enough to reveal measurable phenomena but not so large as to become hazardous to users. This paper presents theoretical underpinning and experimental verification of a fluid mechanics lab experiment appropriate for undergraduate engineering students that 1) meets all the above-described criteria, 2) costs less than $30 in materials, and 3) can be easily mailed to remote learners.
