I have a system that uses a bellows to pressurize air in a fluid reservoir with a small exit tube. I am trying to model the flow rate of the fluid over time. I am assuming PV=C, and that dV/dt=(P-Pa)*K, where C and K are constants.
The air volume (including bellows) is large compared to the...
I am trying to illuminate a surface with light from a light guide. At the distance I am using, the spot is 7mm dia, but the surface is 7x28. Can I use a plano-concave cylindrical lens to stretch the spot 4:1 in one direction? If so, how can I calculate the object distance given the focal...
Just a basic theoretical question (or three):
I know that it is desirable to have the natural frequency of a system be far away from any driving frequencies.
-Is there any inherent advantage to having the natural frequency above the driving frequency? If I look at an output magnitude vs...
As I mentioned in another thread, I am looking at a fluidics analogy of an RC circuit to filter out pressure fluctuations. The R is just a constriction, but the C has to be a "balloon", with a relatively linear change in volume vs. pressure. I am thinking of peristaltic tubing, but...
I am trying to eliminate pump pressure fluctuations in an analytical instrument. We have a few unique constraints.
1. The sensor itself is sensitive to ~.1psi fluctuations, and is at about .5psig
2. We are very sensitive to mixing of the sample fluid with the preceding buffer, so tees or...
