Temperature drawing

With high temperatures the x values will not fit into the diagram. Then the hj values have to be calculated with smaller x values in order to draw the isotherms. In Table 4.6 these values are calculated with values x = x q% at various temperatures. Drawing the fundamental axes and isotherms with the instructions given above and the saturation curve with the help of Table 4.6 leads to the Mollier diagram in Fig 4,10u. 

Plot a graph of the mass of salt dissolved versus temperature. Draw a best-fit smooth curve through the data points. With the help of your teacher, obtain solubility data from the other groups in your class for the remaining three salts. Graph this data on your graph to obtain a family of solubility curves. 

This feature will be increasingly Important as battery manufacturers continue to increase the cell capacity with thinner separators. The pore structure is usually influenced by polymer composition, and stretching conditions, such as drawing temperature, drawing speed, and draw ratio. In the wet process, the separators produced by the process of drawing after extraction (as claimed by Asahi Chemical and Mitsui Chemical) are found to have much larger pore size (0.24—0.34 fixxi) and wider pore size distribution than those produced by the process of extraction (0.1—0.13 after drawing (as claimed by Tonen). ...

Rerun Van Der Waals.m but with different operating conditions in terms of temperature and pressure for the same material. Take, for example, water at room temperature (300 K) and change the pressure from atmospheric maximum up to 32 atm (beyond which the vdW equation predicts one single phase, i.e., the liquid phase) and see how the calculated Z is affected by changing the pressure for the same material at a fixed temperature. Draw a conclusion up to what maximum pressure (atm) one can use the ideal gas law for water vapor (i.e., 2= 1.00+0.1). Does it make sense why we use the ideal gas law for an air/water mixture at atmospheric conditions in humidification, air conditioning, and drying/evaporation processes ... 

In conventional extrusion the maximum pressure that can be applied without stick-slip is around 0.23 GPa and so this provides a "process dependent" restriction on extrusion rate and the maximum draw ratio available. In push-pull extrusion, forces up to the tensile fracture of the material can be applied so the true maximum draw ratio for the material at a given temperature can be obtained. The limit of temperature and draw ratio detected in these studies has been added to the extrudability map (Figure 6) showing the maximum regions of the temperature/draw ratio map that may be studied. Clearly the push-pull process greatly extends the range of the extrusion technique. A series of samples prepared at the same draw ratio and temperature, but with different combinations of push and pull, have the same modulus, i.e. mechanical properties are independent of the applied pressure. 

An aromatic copolyamide (7) which does not form nematic solutions due to its reduced chain rigidity is also used for the production of HSHM fibres. It appears that the chain rigidity is sufficient for the formation of a nematic mesophase in the absence of solvent, and this probably occurs during the high temperature drawing of the fibres, which are spun from conventional solutions.
