A piston-cylinder assembly contains Refrigerant 22, initially a saturated vapor at 5 bar. The refrigerant undergoes a process for which the pressure-specific volume relationship is pv = constant to a final pressure of 20 bar. Kinetic and potential energy effects can be neglected. a. For your schematic, provide a rough sketch of your system, with arrows indicating direction of work and heat (i.e, in or out of the system) b. Determine the work and heat transfer for the process, each in (kJ/kg)
As shown in the figure, Refrigerant 22 enters the compressor of an air conditioning unit operating at steady state at 40°F, 80 lb;/in? and is compressed to 160°F, 200 Ib;/in?. The refrigerant exiting the compressor enters a condenser where energy transfer to air as a separate stream occurs, and the refrigerant exits as a liquid at 200 Ib:/in?, 90°F. Air enters the condenser at 70°F, 14.7 lb:/in? with a volumetric flow rate of 750 ft/min and exits at 110°F. Neglect stray heat transfer and kinetic and potential energy effects, and assume ideal gas behavior for the air. Condenser Air at T P4=14.7 1bf'in.?

Air enters a diffuser operating at steady state at 540°R, 15 Ilbf/in.?, with a velocity of 600 ft/s, and exits with a velocity of 60 ft/s. The ratio of the exit area to the inlet area is 6. Assuming the ideal gas model for the air and ignoring heat transfer, determine the temperature, in °R, and pressure, in Ibf/in.?, at the exit.
