In the cp = 1.33 design of plastic capped bottles. if the diameter of the bottle was 1" +/- .003", and the manufacture of the cap yielded +/- .004", indicate the nominal of the cap using worst case design (one answer only)

a. 1.003
b. 1.004
c. 1.005
d. 1.006
e. 1.008

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

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?

The power source in a certain welding setup generates 3500w that is transferred to the low carbon steel work with a heat transfer factor of 0.85. the melting factor in the operation is 0.45. a continuous fillet weld is to be made with a cross-sectional area of 23 mm2 determine the travel speed at which the welding can be accomplished.
