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)

Asimple speed reducer is composed of 2 spur gears. the pinion gear has a pitch diameter of 0.75" and 36 teeth while the driven gear has a pitch diameter of 4.0" and 192 teeth. a)-what is the diametral pitch of each gear? b)-if an electric motor rotating ccw at 3000 rpm is coupled to the pinion, what is the rotational speed of the driven gear? c)-if the torque delivered to the pinion is 1 n-m, what is the torque on the driven gear? d)-what is the power transmitted by the gear train?
