Refrigerant R-134a at 1.2 MPa and 75

°C is condensed to a saturated liquid in

a condenser at constant pressure. Air is

employed to extract the thermal power

from the refrigerant. The temperature

of air with a mass flow rate

of 126,165.3 kg/h increases from 9 °C

to 45 °C. Determine the mass flow of

the refrigerant in the device. Take the

specific heat of air to be 1.005 kJ/kg

and give your answer in kg/s to 1

decimal place.
