Hey Everybody! It's my first time posting here, so please forgive any errors that might creep into this post. I'm a guy who loves physics. In fact, it has been my favorite subject ever since I can remember, and in physics, the field that attracts me the most is kinematics. Well, the question I have is about fluid flow, specifically, the pressure of a fluid. I've never been good at fluid dynamics and kinematics so if this sounds like an idiotic question, I'm sorry in advance. Everywhere I read, it is said that fluid pressure is inversely related to the speed of the flow. Meaning that if a fluid is flowing through a pipe at a flow rate of say, 10Kg/second, it will be exerting more pressure than it would if it were flowing at a rate of 5Kg/second. Basically, it means that in order to increase the pressure of a fluid, you have to slow it down and expand its volume. This seems so counter-intuitive! By extension, if a fluid is at rest, mass flow rate is 0Kg/sec and it's volume is made infinite, it must have infinite pressure?! This means that the air in the room I'm sitting should be at an infinite pressure and crush me immediately! But that is not the case. Basically, what I'm saying is that if I can increase the pressure by decreasing the speed of fluid flow, then is not a fluid at rest also at infinite pressure? So what is pressure? I always thought that pressure was generated by confining a large amount of fluid in a small volume. The more the fluid and the smaller the volume, the higher the pressure. Am I right or wrong? And what's with the fluid pressure while it's flowing? I look forward to your answers as I have registered with physics forums specifically for asking this question. Thanks, Mak.
