What is Heat Exchanger Performance Analysis about?

The document describes a condenser used in an automobile air conditioner. At a velocity of 40 mph and ambient temperature of 95°F, the condenser removes 60,000 Btu/h from Freon 12 at 150°F, with a 10°F rise in air temperature. The heat transfer coefficient is 35 Btu/h·ft2·°F. As velocity decreases from 40 to 10 mph, air mass flow decreases directly with velocity, while the heat transfer coefficient decreases as the 0.7 power of velocity. The question asks to plot the percentage reduction in condenser perfor
