Question:
Working for an automotive journal, you are reviewing two proposed new models that have identical frame shapes and identical masses. Car 1 runs on a Brayton cycle that does enough work to accelerate the car from 0 to \(100 \mathrm{~km} / \mathrm{h}\) in \(11.5 \mathrm{~s}\) when internal friction, air resistance, and other retarding factors are left out of the equations. When air resistance is taken into account, the car's top speed is \(105 \mathrm{~km} / \mathrm{h}\). In the cycle, the isobaric cooling is accomplished by exposing the working substance to normal atmospheric pressure and \(350 \mathrm{~K}\), the temperature under the car's hood. When the working substance is compressed, the pressure increases by a factor of 5.00, and the temperature of the working substance after the isobaric combustion is \(700 \mathrm{~K}\). At the compressor, the engine takes in \(1.00 \mathrm{~mol}\) of the working substance (which the designer has modeled as having four degrees of freedom) and the operating speed is 8.00 cycles/s. Car 2 runs on a Carnot cycle that has the same minimum and maximum temperatures of \(350 \mathrm{~K}\) and \(700 \mathrm{~K}\), the same fuel intake, and the same piston volume. The frame shapes and masses of the cars are nearly identical. The only difference (other than the cycle itself) is that car 2 runs at only 1.00 cycle per second.
