Question

What is the most efficient cycle than can be executed and a sink at temperature tou_c? Rankine cycle Otto cycle How do the efficiencies of the Otto and Diesel cycles compare same compression ratio? Eta_ch.Otto > eta_th.Diesel eta_th.Otto = eta_th.Diesel it cannot be determined In an actual gas-turbine cycle, how can the deviation of actual compressor and from the idealized isentropic behavior be accounted for by reducing the back work ratio by assuming a higher working pressure of the turbine compressor it cannot be accounted for On a T-s diagram, what does the area under the process curves represent for an internally reversible process? The boundary work of the process The net work of the process The heat transfer of the process The irreversabilities of the process Which of the following lists of properties includes only properties? pressure (P). temperature (T), mass (m), specific volume (v) mass (m), volume (V). total energy (E). total internal energy(u) density (p), temperature (T). specific internal energy(u), pressure (p) temperature (T), volume (V), density (D), pressure (P)
