Organism (8/13)



  1. Water pressure P=(density). g h But, air is compressible fluid. Air density is not constant. It is a function of pressure, P. And, other factors, i.e., temperature, humidity, etc. give an influence on pressure. They can vary with altitude.
  2. Without an existance of the background back side something, transforming from energy to particle can happen? At the BigBang point, the high energy seperate away the background back side particles too far. But, current low collision energy does not have a capacity to push away the background back side particles so far. So, antimatters are background back side particles which exist not so far away ?
  3. For safety Is this calculation wrong? FB =~ 5 x total load + platform weight + two pontoons weight FB =~ 4 x total load +700+ two pontoons weight
  4. Other factors, i.e., humidity, temperature variation according to altitude are not considered.
  5. This is a calculated result by using this equation. P2 =P1exp(-C(Z2 -Z1)) T=25oC
  6. On the ground, Z=0 [latex]\Delta P=-\rho \ g \ \Delta Z[/latex] From the ideal gas equation. [latex]\rho =\frac{PM}{RT}=K \ P[/latex] If T is constant, K=constant [latex]\Delta P=-C \ P \ \Delta Z[/latex] C; constant [latex]\Delta Z \rightarrow 0[/latex] [latex]d P=-C \ P \ d Z[/latex] Pressure equation Let [latex]Z_{1}=P_{1}, \ Z_{2}=P_{2}[/latex] [latex]\frac{P_{2}}{P_{1}}=exp (-C \ (Z_{2}-Z_{1}))[/latex] [latex] C =\frac{gM}{RT}[/latex]
  7. In the case of solving mathematical equations, using dimensionless forms of the equations is more reliable.
  8. Paper chromatography. Carrier liquid is water, water+ethanol or water +methanol, etc..
  9. In general, the piston type compressor is used at the high pressure compression. We can control the compression ratio by reducing the empty space. However, without good sealing, the compressor can not generate high pressure gas output.
  10. This Figure represents the intensity of Coriolis effect with latitude.
  11. This is a Figure about the coriolis effect. The first Figure is about the height effect, and then, the second Figure is about the latitude effect.
  12. Before doing this experiment, have you done any experiment about the reference reagents by using the same apparatus? Quantitative experiment always should be exact, even the experiment is in the elementary course.
  13. The main compression is occuring at the upper part of the machine. Botton part sealing state is not so good. To maintain a good sealing state , suitable spring pressure is required. Sealing is one of the important factor in the compressor design.
