Steam enters a partially open valve operating at steady state as satu-rated liquid at 300°F and exits at 60 lbf/in.2 Neglecting kinetic and poten-tial energy effects and any stray heat transfer with the surroundings, deter-mine the temperature, in °F, and the quality of the steam exiting the valve

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

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.

The drive force for diffusion is 7 fick's first law can be used to solve the non-steady state diffusion. a)-true b)-false
