For a 68 wt% zn–32 wt% cu alloy, make schematic sketches of the microstructure that would be observed for conditions of very slow cooling at the following temperatures: 1000°c (1830°f), 760°c (1400°f), 600°c (1110°f), and 400°c (750°f). label all phases and indicate their approximate compositions.

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit. explain why the pneumatic piston stumbles when it hits an obstacle.

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.

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false
