Hi S.E., I have attached a drawing. the valves are basically there to redirect flow. "Flow merely describes the flux through a cross section of the pipe. The pressure of the fluid on the pipe wall is what will cause stress in the pipe itself. Have you taken a course in mechanics/strength...

Hi S.E., thank you for your reply. "A) If I'm reading your question properly, by closing the valve it is no longer steady state and thus the continuity equation can not be applied. At this point all that will be moving the fluid is inertia and gravity. If I misread what you wrote and the...

[b]1. Good day to all. Would appreciate all your help for my understanding please. I am quite new to this topic of fluid dynamics. a) Say i have a 1200mm pipe which eventually serves a main distribution network. However, I will close the valve to the distribution and allows the water to...

dear mfb and travis, thanks for your replies! If possible, do yall mind elaborating more on why the above is so? Otherwise, you have already been very helpful :)

mfb and travis, thanks for the clarification. indeed, it is not quite possible to make the system symmetric. However, assuming that it is, say that i have pipe a compressor initially delivering compressed air at 6 bar, with only one pipe, the pressure in the pipe may only be 5 bar due to...

Hi Mr watters, thanks for your reply! Could you explain to me why this is so though? Does the equation P1V1 = P2V2 apply here? As the pressure drops, will the volume of the compressed air increase due to expansion? Thanks again!

Good day to all, was wondering how a pressure regulator doownstream will affect the flow rate of compressed air through a pipe. Anyone has any insights on this? the pressure regulator is to reduce the downstream pressure but I'm really confused how the flow will be affected. For instance, will...

Hi mfb, apologies, i didnt post my reply to you. Thanks for your reply anyway! Can i clarify please, am i right to say that from what you stated, assuming that the system is symmetrical, flow will be halved such that each pipe will have equal flow and pressure in each pipe will be higher than...

Hi travis, the pipes lead to a diffuser about 6m deep. It is for aeration purposes. Demand wise, sometimes demand is long and continuous (4hrs or longer), at other times it is short and intermittent (10mins on, 10mins off etc.).

Hi all! I have a problem here, anyone here knows what will be the effect on pressure and flow rate of compressed air by adding additional pipes leading out from my compressor? For eg. if i were to increase the number of delivery pipes from 1 to 2, will the flow be slpit evenly between the two...
