Fthe tires on an automobile are checked with a standard tire gauge having graduations at 5-psi increments (psi=lb/in2), evaluate the this gauge for accuracy, precision, reliability, validity, and subjectivity.

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.
