- Effect of Molecular Weight On Compressor Performance
Dear All, I have extensively studying the analysis of the impact of Molecular weight changes on fixed speed and variable speed compressors Can you provide your feedback on the below simplified summary: 1) Fixed Speed Compressor, fixed compression ratio, speed and head at every flow: a) With
- Pressure Difference due to Altitude | Eng-Tips
The gauge pressure of the gas is the difference between the absolute pressure inside the column and the air outside, i e 103,6 - 100,1 = 3,5 kPag In summary, the gas pressure at the base of the column is 104,3 kPa abs and at the top it is 103,6 kPa so this shows that the absolute pressure is highest at the base of the column
- Wind effect on heat loss gain through walls | Eng-Tips
In cooling the difference between indoor and outdoor temperature factors in mainly on infiltration and ventilation The heat gain through walls is more about the heat from the sun beating on the wall, than it is the temperature differential between indoor air and outdoor air
- Difference between surface contact mesh and mesh mating condition
I am using NX 7 5, my doubt is applying these contact mesh will it affect the weld mesh which are there in the contact region and if yes what will be the effect
- Internal wind pressure | Eng-Tips
So when you get a net difference between a set internal pressure and a different exterior pressure, you get a net pressure applied to the walls of the box This is not necessarily the full internal pressure effect used in ASCE 7
- Please help clarify datum shift vs bonus tolerance | Eng-Tips
Then the datum shift is the difference between the actual size and the virtual condition size developed by the refinement tolerance If the same hole was a tertiary, the the shift is the difference between the actual size and the virtual condition size developed through the positional tolerance rather than the refinement
- AGMA 11 VS AGMA 9 Specification Whats the real word differerance
If you have high pitch line velocities in your mesh or heavy loads, the difference in quality class between 9 and 11 can have a significant effect on dynamic tooth loads, tooth contact stresses, vibration and noise
- Bourdon effect | Eng-Tips
the bourdon effect is the difference between the pressure inside the tube or pipe in relation to the pressure outside the tube or pipe If the inside presurer is greater than the outside presure the tube or pipe will expand
