The pump is operating so that the axial velocity at the inlet to the first stator is 10 m/s . The tangential velocities are zero before the first stator, Vt=−1.2m/s after the first stator, Vt = 1.5 m/s after the rotor, and zero after the second stator. What torque does the fluid exert on the pump's stators? The diameters are d1 = 12 cm and d2 = 16 cm and the fluid density is rho = 1000 kg/m3 .

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?
