If the air around the condenser experiences a temperature rise of 15 °F, what is the mass flow rate<br />
of air via a fan across the condenser’s coils?<br />
Estimate the CFM (ft 3 /min) of air flowing across the condenser coils<br />
Can you draw a T-s diagram <strong>and</strong> trace the refrigerant as it goes through from device to device?<br />
Can you draw an pressure –enthalpy (p-h) diagram as this is what was normally used to get<br />
enthalpy values prior to the days of computers <strong>and</strong> tables?<br />
