If air velocity at 21.1 m/s is desired, what is the expected difference between stagnation and static pressure read by a water manometer in inches H2O at this air velocity if the air pressure is 100 kPa and 20 Celsius?

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?
