Acylindrical rod of copper originally 16.0 mm id diameter is to be cold worked by drawing; the circular cross section will be maintained during deformation. a cold-worked yield strength in excess of 250 mpa and a ductility of at least 12%el are desired. furthermore, the final diameter must be 11.3 mm. using the graphs below, explain how this can be accomplished.

Ir at sea level and 30°c and 50% relative humidity flows at a rate of 1 kg/s through a cooling coil that has an apparatus dewpoint of 10°c. the air leaves the coil at 15°c. determine the following: 3.1)- relative humidity of the air leaving the coil; 3.2)- moisture content of the air leaving the coil; 3.3)- sensible heat factor; 3.4)- total heat transfer rate; 3.5)- sensible heat transfer rate 3.6)- latent heat transfer rate
