A specimen of a 4340 steel alloy with a plane strain fracture toughness of 54.8 MPa1m (50 ksi1in.) is exposed to a stress of 1030 MPa (150,000 psi). Will this specimen experience fracture if the largest

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.
