The volume of a 1-kg copper sphere is not allowed to vary by more than 0.1%. if the pressure exerted on the sphere is increased from 10 bar while the temperature remains constant at 300 k, determine the maximum allowed pressure, in bar. average values of rho, β and κ are kg/m^3, 49.2 × 10^-6 (k)^-1, and 0.776 × 10^-11m2/n respectively

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

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.

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