A gas within a piston-cylinder assembly executes a Carnot
Chapter 5, Problem 5.76(choose chapter or problem)
A gas within a piston-cylinder assembly executes a Carnot power cycle during which the isothermal expansion occurs at \(T_{\mathrm{H}}=600 \mathrm{\ K}\) and the isothermal compression occurs at \(T_{\mathrm{C}}=300 \mathrm{\ K}\). Determine
(a) the thermal efficiency.
(b) the percent change in thermal efficiency if \(T_{\mathrm{H}}\) increases by 15% while \(T_{\mathrm{C}}\) remains the same.
(c) the percent change in thermal efficiency if \(T_{\mathrm{C}}\) decreases by 15% while \(T_{\mathrm{H}}\) remains the same.
(d) the percent change in thermal efficiency if \(T_{\mathrm{H}}\) increases by 15% and \(T_{\mathrm{C}}\) decreases by 15%.
