1. For gases and other compressible fluids , it depends on temperature and varies very slowly with pressure. 2. The relation between flow rate and inlet pressure is calculated with Poiseuille's equation for compressible fluids . 3. I never heard of the use of compressible fluids , but that would probably suffer the same problem. 4. The term "'safety valve "'should be limited to compressible fluid applications ( gas, vapor, or steam ). 5. This vector is of interest both in compressible fluids and in incompressible ( but inhomogeneous ) fluids. 6. Since the cavity is filled with air, mechanical amplification is lower than hydraulic machinery with a non-compressible fluid . 7. One can use the crossings of the characteristics to find shock waves for potential flow in a compressible fluid . 8. By contrast, the behavior of compressible fluids , and especially gases, demonstrates the essence of elastic energy with negligible complication. 9. The flow of a compressible fluid through an orifice is limited to the flow at sonic velocity in the orifice. 10. :: It seems like the effect of weights can be mimicked in many ways, such as with springs and / or a compressible fluid .
