Calculate the efficiency of a hydrogen production system for a future transportation alternative for the cases of: 1. A nuclear system using the Steam Cycle with an overall thermal efficiency of 33.3 percent, 2. A nuclear system using the Brayton Gas Turbine Cycle with an overall thermal efficiency of 60 percent.

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.
