Moist air at 27°c, 1 atm, and 50% relative humidity is heated in a constant pressure process to 45°c. determine the heat transferred to the moist air per kg dry air [kj/kg dry air] you may assume the mixture behaves as an ideal gas.

Assuming compressible flow of air and that the measurements are done at flagstaff a pitot static tube that gives the difference of total and static pressure measures 0.35 m of mercury. what is the velocity of air? assume the temperature to be 300k. (submit your excel or matlab calculation sheet)

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 sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false
