Description :

　　Principles of Chemical Engineering Experimental Device - Bernoulli Experimental Device

　　Purpose of the experiment:

　　1. Familiarize oneself with the concepts and conversion relationships of various energies and pressure heads in fluid flow, and deepen the understanding of Bernoulli's equation.

　　2. Observe the variation of various energies (or pressure heads) with flow velocity.

　　Main configuration:

　　The Bernoulli experimental setup mainly consists of a water storage tank, a water pump, a high-level water tank, a rotor flowmeter, a Venturi tube, a pressure measuring tube, and a stainless steel frame.

　　Heat exchanger is not only a universal process equipment widely used in various industrial sectors such as petroleum, chemical production lines, fertilizers, power, metallurgy, transportation, etc., but also an effective device for waste heat recovery and utilization. Shell and tube heat exchanger is currently a commonly used structural form of heat exchange equipment in thermal systems. The support structure of the tube bundle is the key structure of the shell side, which can generate the desired flow pattern of the shell side fluid and is an important factor in determining the heat transfer and flow resistance performance of the heat exchanger. Different shell side fluid flow patterns result in significant differences in the heat transfer and flow resistance performance of the heat exchanger.

　　Compared with developed countries, there are indeed many urgent problems to be solved in the domestic chemical industry.

　　1. The large number and small scale of enterprises, with a dispersed layout, cannot have a significant impact on the international market;

　　2. The low product quality, coupled with insufficient scientific research and innovation capabilities, results in low technological content and added value of the product, making it difficult to form a competitive flagship product;

　　3. The production line has low flexibility and insufficient personalized production capacity, making it unable to adapt to the rapidly changing and increasingly diverse market demands;

　　4. The high cost is a common problem faced by any industry and enterprise, but it is particularly prominent in the domestic chemical industry.
