A1.80 m wide and 5.0 m long plate moves through a stationary air of density 1.22 kg/m3 and viscosity 1.8x 104 poise at a velocity of 1.75 m/s parallel to its length. determine the drag force on one side of the plate by assuming (i) laminar flow (ii) turbulent flow

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?
