Gold forms a substitutional solid solution with silver. compute the weight percent of gold that must be added to silver to yield an alloy that contains 6.5 × 1021 au atoms per cubic centimeter. the densities of pure au and ag are 19.32 and 10.49 g/cm3, respectively. the atomic weights for gold and silver are 196.97 and 107.87 g/mol, respectively.

On a average work day more than work place firs are reorted

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.

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.
