(10) A refrigerant 22 refrigerating system is operating with a condenser temperature of 42°C and an evaporating temperature of 0°C. (a) If the liquid line from the condenser is soldered to the suction line from the evaporator to form a simple heat exchanger and if as a result of this the saturated vapor leaving the evaporator is superheated 10 degrees, how many degrees will the saturates liquid leaving the condenser be subcooled? Determine (b) the volume flow rate, and (c) the compressor work. Ans. (a) 5.3°C, (b) 1.102 L/s/TR, (c) 0.662 kW/TR

Strengthening of the alloys is required as metals become weak due to various lattice defects, metal bonding phenomena. The strength of the metals is not enough for any mechanical work. The internal dislocations of any metals arise due to forming processe…
