Question:

(a) An air-cooled condenser transfers heat at the rate of 12(Btu) s-1 to ambient air at 70((F). If the air temperature is raised 20((F), what is the required volumetric flow rate of the air?
(b) Rework Part (a) for a beat-transfer rate of 12 kJ s-1, ambient air at 24(C. and a temperature rise of 13(C.
