°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.
