How many trains have been invented all around the world?

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.
