Refrigerant-134a enters the compressor of a refrigeration system as saturated vapor at 0.14 mpa, and leaves as superheated vapor at 0.8 mpa and 60°c at a rate of 0.06 kg/s. determine the rates of energy transfers by mass into and out of the compressor. assume the kinetic and potential energies to be negligible.

An air-standard stirling cycle operates with a maximum pressure of 600 psia and a minimum pressure of 10 psia. the maximum volume of the air is 10 times the minimum volume. the temperature during the heat rejection process is 100°f. calculate the specific heat added to and rejected by this cycle, as well as the net specific work produced by the cycle. use constant specific heats at room temperature. the properties of air at room temperature are r

Most of the volume of an atom is occupied by the
