You are designing an engine that contains several pistons that each move \(150 \mathrm{~mm}\) per stroke. You believe the engine may consume less energy than a traditional engine if many of the processes in the engine are reversible. The gas is a mixture of several substances, but the particles have an average mass of \(7.548 \times 10^{-26} \mathrm{~kg}\) per particle, and the gas temperature can reach \(300^{\circ} \mathrm{F}\). Determine an upper limit on the number of cycles a piston can go through each second, and satisfy the reversibility constraint. How could this upper limit be increased? Is the reversibility constraint sensible?
