Asmall piece of ultra-thin film is cured in an oven with wall temperature of 200 °c. air at 20 °c flows over the plate with h = 15 w/m^2 k, and the film has an emissivity of ε =0.5. what is the temperature of the plate? assume steady state.

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
