Refrigeration and Air Conditioning A refrigerating system operating on reversed Brayton refrigeration cycle is used for maintaining 250 K. If the temperature at the end of constant pressure cooling is 300 K and rise in the temperature of air in the refrigerator is 50 K, then the net work of compression will be (assume air as working substance with Cp = 1 kJ/kg) 100 kJ/kg 25 kJ/kg 125 kJ/kg 50 kJ/kg 100 kJ/kg 25 kJ/kg 125 kJ/kg 50 kJ/kg ANSWER DOWNLOAD EXAMIANS APP
