An ideal vapor-compression refrigeration cycle operates at steady state with refrigerant 134a as the working fluid. saturated vapor enters the compressor at 0°c, and saturated liquid exits the condenser at 7 bar. the mass flow rate of refrigerant is 0.08 kg/s. determine (a) compressor power in kw, (b) the refrigeration capacity in tons, (c) the coefficient of performance of refrigerator

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m
