Hi everyone, My objective is to create a quantitatively accurate simulation of a column buckling. Ideally, I would like to apply a compressive axial force at or just above the critical load to an initially straight column (perhaps with a small perturbation) and see it transition from the...

I agree that if the total pressure is the same at the two inlets, then in order to have the same static pressure at the two inlets as well, the flow velocity would also need to be the same. Flow rate could be different. I'll go into more detail about what I am considering, to make sure I...

Okay great, thanks guys. I'll look more into the regulators.

Well, consider a simple network of pipes. Two inlets and one outlet. The outlet is into atmosphere. One way to drive flow through network is to hook up the two inlets to the same reservoir. Now, the pressure of the reservoir should be treated as a total pressure at the inlets when solving for...

Hi everyone, Is there any mechanism/method/device to control static pressure? Noting that, total pressure = static + dynamic pressure. The scenario I am thinking is just water flowing through a pipe (assume incompressible), and I want to control the static pressure at two points along the pipe...

Excellent! Thank you very much for the explanation and sources.

Hi, I need clarification on the difference in head loss for turbulent flow and laminar flow. I understand how the head loss due to friction is different for the two regimes. For friction head loss, the friction factor is 64/Re for laminar flow, and a more complex formula for turbulent flow. I...

Hi, I am a math and physics major planning on going into biophysics for grad school, and i want to do computational/mathematical modelling/theoretical work in the field. I have one more math course to take and I am not sure which would be more useful. Here are their very brief course...

Thanks for the advice/information! While i am a senior technically (by number of hours) i will be in school a couple more years in order to get through the physics program. Consequently, i will have time to do undergraduate research, plus i will be doing an honors thesis. Additionally, i could...

Im currently a senior at a large state university (LSU), and have been studying economics(major) and math(minor) and have a 4.0 so far. Recently i decided i did not want to pursue economics, and became much more drawn to the pure sciences. I decided to stay in school and study physics and bump...

Point taken. This was an initial thought i had myself. All the action is occurring a few levels above the quantum. Hopefully, as I am sure it will, my interests will solidify a little more as I progress through the physics curriculum. I really just needed to know now to what extent i need to...

Thanks a lot for the info from both of you. Very helpful. I figured that studying the brain at the quantum level is not taking place at the moment due to, among other things, the fact that researchers are only scratching the surface in neuroscience. However, I am also only 21, so there will be...

My situation: I was originally an Economics major, math minor. However, I have lost interest in econ and have become very interested in physics and math. I begin my senior year of undergrad this fall, however I am staying in school longer and beginning the physics curriculum as well this...
