On the principle of steam jet pumps

2013-12-31View Original

Thread Content

It is based on steam passing through a narrow diameter, which results in low pressure; it’s not clear why low pressure is generated – is there any formula to explain this? There’s also the issue of throttling expansion, during which the temperature drops. Why does the temperature decrease? Is there a formula to explain it? I just don’t feel like I have a deep understanding of it

PV=nRT, you know. When going from a small diameter to a larger space, V increases while P decreases. Due to the increase in volume, work is done on the surroundings, the internal energy decreases, and the temperature drops. KO!

It’s not hard to understand if you have some knowledge of chemical engineering principles; take a look at Bernoulli’s equation

In the principles of chemical engineering, the Bernoulli equation can be used to solve such problems

It has been answered on the upper floors; Bernoulli’s equation

Bernoulli’s equation, the conversion between kinetic energy and static pressure energy

Bernoulli’s equation, conservation of mechanical energy
