So it means the chamfer can just be ignored, since the projected area of the chamfer + the area of the flat surface is the same as just the area of the completely flat piston?

I was reading up on forces on hydraulic/pneumatic cylinders, and I've been thinking of this for a while: So for a pneumatic cylinder, the force on the piston is simply: P = F/a F = P x a where a = area of the piston that the air pressure is acting on. So what would happen if the piston is...

Is this not done simply by dividing the volume of the 25 inch3 by 11.26 seconds?

Thanks for the replies. I'm not actually planning to make one, I just find it easier to apply the knowledge to simple real world examples to better understand it, thanks. So it's pretty much: Get the required flow rate Set an acceptable pressure drop (i.e. the min pressure at the outlet/use...

Hi all, I'm an old tinkerer with a hobby on reading science and engineering topics. Specialty is on machining but I enjoy reading up on a broad variety of topics. Nice to meet you all :smile:

Hi all, I'm a tinkerer with no formal engineering background, but enjoy read about physics and engineering in general. I'm reading up on fluid flow and I'm a bit grasping at the concepts. As far as I understand it, flow rate, pressure drop and pipe size are all interrelated, where one affects...
