A second class lever is used to lift a 600 lb load. The length from the fulcrum to the center of the load is 9 ft. The length from the fulcrum to the effort is 16 ft. What is the ideal mechanical advantage of the system?

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.
