Suppose that all the dislocations in 2000 mm3 of crystal were somehow removed and linked end to end. Given 1 m =0.0006214 mile, how far (in miles) would this chain extend for dislocation densities of

(a) 103 mm-2 (undeformed metal)?

(b) 1010 mm-2 (cold-worked metal)?

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.
