Air Is Cooled and Dehumidified as It Flows Over the Coils

Air is cooled and dehumidified as it flows over the coils of a refrigeration system at 90 kPa from 25°C and a humidity ratio of 0.021 kg/kg dry air to 15°C and a humidity ratio of 0.015 kg/kg dry air. If the mass flow rate of dry air is 0.7 kg/s, the rate of heat removal from the air is

A) 6.8 kJ/s
B) 11 kJ/s
C) 45 kJ/s
D) 32 kJ/s
E) 18 kJ/s
