The total current in a series circuit is ___ amps. The circuit is supplied from a 2-pole breaker in a 120/208-V 3ph panel. The circuit has a resistance of 25 ohms, an inductive reactance of 14 ohms and a capacitive reactance of 10 ohms

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.
