Se desea enfriar 1000 lb/h de una corriente de etileno (C2H4) gaseoso que se encuentra a 300 0C en un enfriador que opera a régimen permanente, si la temperatura de salida es de 50 0C. Calcular la carga térmica del enfriador si el enfriamiento se lleva a cabo con agua líquida que se encuentra inicialmente a 20 0C y cuya temperatura no debe de aumentar más de 10 0C. (Base una hora de operación). Nota: Cp (C2H4) = 13.65 cal/mol °C

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.
