5-4. Consider a reciprocating compressor operating with R-134a. Refrigerant enters the cylinder at 20 psia (138 kPa) and 20 F (-7 C), but leaves the evaporator saturated at 0.5 F (-18 C), The vapor is discharged from the cylinder at 180 psia (1.24 MPa). Compute the volumetric effi ciency for (a) a clearance factor of 0.03, and (b) a clearance fac tor of 0.15. (c) Compare the mass flow rates for parts (a) and (b), and (d) compare the power input to the compressor in arts (a) and (b)
