Steam enters a nozzle at 400°c and 800 kpa with a velocity of 10 m/s, and leaves at 300°c and 200 kpa while losing heat at a rate of 25 kw. for an inlet area of 800 cm2, determine the velocity and the volume flow rate of the steam at the nozzle exit.

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
