A40 wt% pb–60 wt% mg alloy is heated to a temperature within the α + liquid-phase region. if the mass fraction of each phase is 0.5, then estimate:

(a) the temperature of the alloy
(b) the compositions of the two phases in weight percent
(c) the compositions of the two phases in atom percent

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.
